What is USB Memory?
USB memory is one of the smaller storage media that uses USB connectors to connect to many devices, such as personal computers and smartphones, and to read and write data.It′s small and light, so it′s easy to carry and hand over, and it′s easy to use just by inserting a USB terminal into a personal computer, so it′s also a popular recording medium for many people.Flash memory is used to record data in USB memory for fast processing.USB memory is said to be more shock-resistant than HDD, but it is also not suitable for reading and writing data frequently and storing long-term data, so it is one of the media that should be taken to prevent sudden data loss.
USB Memory Not Recognized Symptom Example
When problems such as USB memory connected to a computer do not recognize or read, the following symptoms often occur.
Error messages such as フォーマットMust be formatted する and アクセスInaccessible 」 appear.
The lamp does not light up when the USB memory is connected to the computer.
USB Memory Does Not Appear in My Computer
1. Error messages such as ′Must be formatted′ and ′Not accessible′ are displayed.
When inserting the USB memory into the computer, it says, ′It needs to be formatted.Do you want to format it?′ There are a lot of problems that can occur.
·Examples of formatting error messages
Error Indication OS
Drive: must be formatted to use .Do you want to format it? Windows 10, 8, 7, Vista
The disk is not formatted.Do you want to format it now? Windows XP
The disk that you set was a disk that this computer could not read. macOS iOS
パソコン The message contents are different depending on the computer model and OS.
When USB memory becomes unrecognized, it should be formatted.Do you want to format it?′ and if you press ′Yes′ in a hurry or format it incorrectly, all data stored in the USB memory will disappear.Formatting refers to restoring equipment to its original factory condition.Formatting solves the problem of logical failures, and the USB memory itself may return to recognition, but in most cases, the problem is not solved, and the disadvantages of data disappearing are more noticeable, so don′t do it.If you format it incorrectly, it is important to remove the USB memory from your computer.If you keep plugging it in or trying to do something about it, the data will continue to be overwritten, and if you remove it from your PC immediately, you will not remove the USB memory from your PC, and if you continue working on it, you will often end up in an unrecoverable situation.Let′s be careful.

When USB memory is not recognized, the following message is often displayed on the connected PC.
①inaccessible
②Reconnect the device.
③The USB device is not detected.
④The last USB device connected to this computer is not functioning properly and is not recognized by Windows.
⑤Invalid parameter.
⑥The file or directory is corrupt and cannot be read.
⑦If the device is still not detected, the device may not be functioning properly.
When the USB memory is inserted into the computer or when using it, when some error message is displayed and the USB memory itself becomes unrecognizable, the USB memory itself is on the verge of breaking or has already broken.The condition often deteriorates just by reseating, turning off, or rebooting the USB memory. If you are worried that the data stored in the USB memory is important, missing, or unable to retrieve it, you should remove the USB memory from your PC and try not to get any worse.
2. The lamp does not light up when the USB memory is connected to the computer.
If the USB memory is not detected, check to see if the USB memory lamp in your computer is lit.If the lamp is not lit, it is presumed that the power supply is not working properly.If the power supply is not good and the USB memory lamp does not light up or is not recognized, it may be caused by パソコン malfunction or failure of the computer USB deterioration or damage of the USB port USB damage of the USB hub.
3. USB memory is not displayed in My Computer
There are many cases where USB memory is not displayed in my computer even though the USB memory lamp is lit.This occurs when the computer does not recognize USB memory as a device.If the USB memory is not detected on Explorer or My Computer, USB The USB memory itself is physically faulty or about to break USB The USB port is faulty or damaged デバイス The device driver may be damaged.
What Causes USB Memory Not Recognized?
The following are possible causes of symptoms such as USB memory not being recognized or read.
Bad contact, USB memory not plugged into PC
The USB memory itself is out of order.
USB terminal type is different and size is not correct
a power shortage of electricity
BIOS Configuration Issues
PC malfunction, malfunction, or damage to parts
USB Hub Damage or Defect Occurs
1. Bad contact · USB memory is not firmly inserted into the PC
When symptoms such as USB memory not recognizing occur, the device you want to recognize is often not inserted correctly into your computer or the connection is poor.When using USB memory, make sure that the USB memory terminal is firmly inserted into the USB port or USB connector on the computer side.
2. USB memory itself is faulty
If the USB memory inserted into the PC is not recognized, does not read, or does not respond, the USB memory itself is often broken, so you need to be careful.
①I often use it with my computer plugged in.
②I carried it with my USB memory in my computer.
③I hit and dropped the USB memory against the wall with it in my computer.
④When my computer was submerged, my USB memory got wet.
⑤I had a USB memory in the pencil case, and when I took it out, it was bent.
⑥When I pressed the USB memory hard when it was not detected, it deformed.
⑦USB memory terminal appears to be damaged
There are many cases where USB memory itself is not recognized as a result of a failure.If you have any idea of the items listed above, it is thought that the USB memory itself has failed and you should be careful.After USB memory is no longer recognized, the condition often becomes critical just by reseating, powering on, or rebooting.If the data in the USB memory is important, or if you want to take it out or recover it, you can start by removing it from your computer.Keep using the USB device and don′t touch it even if you want to check the files and folders inside.It is often the case that a recoverable state falls into an unrecoverable state.

How to recover USB memory and restore data | Learn how to deal with each symptom
https://www.adte.jp/rec/hdd/post-953/
USB memory is a small and convenient recording medium for carrying, storing and sharing data.However, since it is small and easy to carry around, it is often shocking, and one day suddenly the USB memory was not recognized or broken, so I accidentally deleted the data.
3. The USB terminal type is different and the size is not right.
There are several types of USB memory terminals.
·Examples of USB memory terminal types
①Type-A
②Type-B
③Type-C
Most USB terminals are Type-A, and Type-A USB ports can only be connected to devices with Type-A USB terminals.Some types of USB memory have Type-C USB terminals instead of Type-A, so let′s check the size.If you can′t connect properly, get dizzy, or are about to come off, it is possible that the USB port has a USB memory with a Type-C terminal in relation to Type-A.
4. Lack of electricity
USB-enabled devices, such as external HDDs, keyboards, and mice, are often powered by a computer.However, connecting such USB devices to a personal computer at the same time may require a lot of power to operate each device, resulting in problems such as USB memory not being recognized or read.Minimize the number of USB devices connected to your computer when you experience symptoms such as not only USB memory but also devices connected to your computer.The situation is often improved by a simple method.
5. BIOS Configuration Issues
The computer contains a program system called BIOS (BIOS) that manages and controls components and connected devices, such as internal components (base/motherboard/storage) and external connections (external HDD/USB memory/keyboard/mouse).If this BIOS setting is changed due to some trouble or the USB device setting is disabled in the BIOS, the USB memory will not be recognized.Let′s check if the BIOS settings are appropriate and there are no problems.
BThe BIOS setting method varies from computer to computer, so you need to look at the manufacturer′s homepage.
6. Computer malfunction, failure, and damage to parts
Problems and failures on the PC and output equipment with USB memory inserted, and contamination, rust, and damage to parts such as USB ports can lead to USB memory not being recognized.If there are multiple USB ports that can connect USB memory, plug it into a port other than the one you always use. If you can use multiple computers, try inserting USB memory into other computers to see if it can be recognized.If the USB memory is not recognized, the problem is often with the computer or the like, not the USB memory side.

What Causes a PC to Break and How to Deal with a Failure?
https://www.adte.jp/rec/hdd/post-1687/
This computer is used in many places such as work, private life, hobbies and schools.You may have thought ′Is your computer broken?′ when you suddenly turned off while using it, your computer couldn′t start, your computer didn′t work with a blue screen or a black screen, and you got an error message.Here are some examples of symptoms and possible causes that occur when a computer fails, such as whether important data is included or whether it should be repaired.
7. Damage or malfunction of USB hub
If it is not recognized when connecting the USB memory using an external USB hub without connecting it directly to the computer, it may be caused by a failure on the external USB hub side or a failure to insert the USB memory correctly into the USB hub.There are three main types of USB hubs, each with a different connection method.
①The type that can be used just by connecting a USB terminal to a PC (bus power)
Many USB memory types are of this type.It will be available after receiving power from the computer.There are many similar types of keyboards and mice.
②The type (self-powered) that allows you to connect an AC adapter to an outlet while connecting to a PC.
Because it can supply power directly from an outlet, it can be used for external HDDs, CD, DVD, BD drives, printers with low power consumption, etc.
③Type with both self power and bus power
It can be used differently depending on the size of the power consumption.
パソコン If the USB memory or external HDD connected to the PC is not recognized, check whether the USB device works or is powered by connecting according to the type.If the USB device is supposed to have power but it doesn′t work, it is estimated that the USB hub is damaged or the USB memory itself that was connected is faulty.
Causes of USB memory failure, physical and logical failures
Symptoms such as USB memory not recognized and suspected equipment failure can be categorized into two categories: physical failure and logical failure.
Physical failure in USB memory
Logical failure in USB memory
1. Physical failure of USB memory
Symptoms such as USB memory not recognized, not read, or not responding are often present, and USB devices are often physically faulty when suspected of failure.A physical failure is a condition in which the equipment itself or the parts inside the data are physically damaged.
·Examples of causes of physical failure of USB memory
Deterioration over time / Overtime of rewriting / Shocked from outside / Submerged / Wet / Dropped / Broken / Broken / Broken / Broken / Left unattended for a long time / Life / Dust accumulated / Broken / Foundation peeled / Rusty / Memory chip damaged etc.
*The flash memory installed in the USB memory will expire depending on the number of times it is used.Due to differences in recording methods, although the upper limit is different, it is generally said that the number of recordings can range from 500 to 100,000.USB memory or SSD is the primary recording medium that uses flash memory.You should also recognize these devices as limited recording media.Please note that frequent reading, writing, video editing, defragmentation, etc. often lead to deterioration of flash memory.Also, if you want to store data for a long time, it may vaporize or disappear when you are not using it, so if you want to store it for a long time, you should also store it on other external HDDs or clouds.
USB In the event of a physical failure of the USB memory, it is difficult for individuals to recover or repair it.Recovering data from flash memory also requires advanced technical skills, deep expertise and experience.By any chance, if you send it to a restoration company without technical capabilities, it may not only be possible to restore it, but it may also worsen the condition.If you have the slightest idea that your USB memory might be out of order, you should give priority to consulting a technically competent data recovery company.
2. Logical failure of USB memory
Logical failure is a condition in which the data, files, and areas that are being managed in USB memory are corrupted memory.
·Examples of causes of logical failure of USB memory
Program problems / Data and system corruption / Software failure / Program file corruption / aging / malfunction / data deletion / virus infection / initialization / format / data read/write / secure removal / USB memory PC suddenly dropped / power outage / lightning strike etc.
·In the event of a logical failure of the USB memory
①No data such as files and folders in USB memory is displayed
②′It needs to be formatted.Do you want to format it?′
③′The file or directory is corrupted and cannot be read.′
④′The parameter is invalid.
Error messages such as are often displayed.
In the event of a logical failure of the USB memory, simply doing what you can, such as reseating the USB terminal, turning it off, and rebooting, can overwrite the data, making it more serious and difficult to recover.If you want to retrieve data or recover it quickly and cheaply, it is important to stop.It is a very dangerous act to work recklessly to do something about it.
Learn what to do if the USB memory is not detected.
If the USB memory connected to the computer is not recognized, please try the following solution.
Visually check the condition
Check USB Memory and PC Connectivity
Checking USB Ports
reseat
reboot
use Device Manager
Reinstall Driver
US>Review BIOS settings
Using Error Checks
Other Workarounds
1. Visually check the condition
If you experience symptoms such as USB memory not recognized or read, start by visually inspecting the USB memory for external damage or scratches.
·Examples of USB memory damage
①be crooked
②rusty
③be piled up with dust and garbage
④be wet
⑤be broken
⑥discolored
Because USB memory is frequently reseated, it is easy to load the USB terminal part, which can cause the USB terminal to bend or peel off the foundation.Also, USB memory is a lightweight and small device, so it is one of the models that often causes problems due to dust and debris sticking to the USB terminal part due to the fact that it was put in the pants pocket without a cover, and carrying it with other things in the brushbox or pouch.First of all, it is important to visually check if there are any abnormalities or damage.
万が一 If by any chance, damage or deformation of the USB memory itself or the USB terminal part can be confirmed by visual inspection, do not try to use it forcibly.It is not only difficult to recover just by reseating and energizing, but it is often impossible to recover.For those who value data or want to recover quickly and cheaply, consult a professional data recovery company immediately.
2. Check the connection between USB memory and PC
If the USB memory connected to your computer is not recognized, check the connection.
①Is the USB memory plugged into the PC properly?
②Is the USB memory lamp on?
③Is the PC receiving power?
④Is there a power shortage?
⑤Is the USB Memory Powered On (Single Power Supply Type)
*If the USB memory is no longer recognized, it is also important to remove all other USB devices connected to the PC once in order to understand the cause.
3. Checking USB Ports
Continuing to use the same USB port may result in poor contact or damage.If you are using a PC with multiple USB ports, connect it to a different USB port to see if the device can detect it.In some cases, only certain USB ports are damaged.If the external USB cable is broken or is likely to be disconnected, you can use a different USB cable to resolve the problem.If you have multiple devices, one of the ways to deal with this is to insert USB memory into another PC and check if it can be recognized.
4. Reseat
If the USB memory connected to the computer is not recognized, try reseating it only once.If it is not inserted correctly or the connection is bad, you can expect to improve the situation by reinserting it.However, you must not try again and again.When the USB memory was inserted into the computer and could not be recognized, the USB memory itself was already broken, the USB terminal was damaged, and the parts inside were often damaged.In such cases, if you repeat the insertion and removal, the condition will become serious, and not only will it increase the difficulty of recovery, but it may also lead to an unrecoverable situation.
5. Restart
When you remove external devices such as external hard drives and USB memory from your computer, you must safely remove them using features such as Safe Removal of Hardware.However, if you remove it without doing this, the communication between the USB memory and the PC will be interrupted in the middle, and the USB memory will not stop working and will be put on hold while the communication continues.If this happens, you will need to restart your computer.Rebooting is an act that puts a heavy load on both PC and USB memory.By any chance, if the USB memory itself is about to break or if it is already out of order, you may end up in an irreversible situation.Let′s reboot only once.If the USB memory is not recognized correctly after restarting the computer, it is estimated that the USB memory itself is faulty, so it is best to contact a professional data recovery company immediately without any unnecessary action.
US>6. Using Device Manager
Device Manager allows you to verify that your computer is able to recognize USB memory.
·How to use Device Manager on a Windows 10 computer
①connect USB memory to a personal computer
②Right-click the Windows mark → Open Device Manager
③Open Disk Drive or Universal Serial Bus Controller
④Check if the USB memory connected to either of の is displayed.
·If the device is not displayed in Device Manager,
①Device Name Does Not Appear in Device Manager
②The device names are marked with ′! Surprise Mark′ or ′? Hatena Mark.′
③USB memory is not displayed in the disk field.
④USB Memory Does Not Appear in Volume List
If you experience symptoms like ~ to の using Device Manager, the connected device is not working properly.·This sign indicates that the PC is not able to load properly load.
デバイス If the USB memory is not displayed in Device Manager, the device itself is often out of order, and it is often impossible to recover just by doing something simple, such as reseating or turning off the power, so try to remove the USB device from your computer.
デバイス If the device is not listed in Device Manager, you may need to reinstall the driver, restore the system, or uninstall updates.However, if you proceed with these operations, you will often lose the stored data, so you need to be careful.Proceed only if you have a pre-backup.If you don′t think you′ve backed up enough or you might not have backed up, don′t push yourself too hard and talk to a professional data recovery company.
′·If ′′Unknown Device′′ is displayed in Device Manager, ′′Unknown Device′′
①Right-click the Windows mark → Open Device Manager
②Remove ′Unknown Device′
上記You may be able to resolve the problem simply by removing the Unknown Device from the above steps.
·Use Disk Management when no problem is found in Device Manager
In Device Manager, you can′t open the files inside even if the USB memory is displayed correctly, and if you don′t have access to data, use Windows′ standard Disk Management feature.Disk Management is a tool that allows you to check the status of your file system.
·How to use Disk Management
①Right-click the Windows mark → Select Disk Management - Windows 10
②Desktop → Move the mouse to the top right → Menu → Settings → Control Panel → System and Security → Administrative Tools → Choose Computer Management (Windows 8/8.1)
·Examples of the display that you would like to be aware of in Disk Management
①′RAW′ appears in the file system field of the USB memory volume.
②Unformatted or Unassigned
③′No Media′ Appears in the Disk Column
①If you see something like ~3, understand it as a sign that the USB memory itself has failed.In this case, if you take unnecessary actions like when USB memory is not displayed in Device Manager, it will not only increase the difficulty of recovery, but you will often end up in an unrecoverable situation, so you should stop touching the device if data is important or you want to take it out.
*By formatting, the USB device itself may be returned to use, but all the data will disappear.Be careful not to format in a hurry.
7. Reinstall Driver
There are two types of USB memory: the type available for drivers that come standard with Windows and the type that doesn′t work without a special driver such as a printer.For USB devices that can be used with standard Windows drivers, the driver will be automatically reinstalled once the driver is removed → connected.If you suspect a driver problem, you may be able to try reinstalling the driver once.
·How to reinstall the driver
①Right-click the Windows mark → Open Device Manager
②Open Universal Serial Bus Controllers and right-click from the list provided.
③Click Uninstall Device or Update Driver Software
④wait a few minutes
⑤Reconnect the USB Memory
⑥Required Drivers Are Automatically Reinstalled
For USB devices that require a dedicated driver rather than a standard driver in Windows, download the driver from the CD-ROM that came with the device or from the manufacturer′s official website.Manual reinstallation of the dedicated driver may also improve the situation.
8. Review BIOS settings
If the USB memory is not detected, you can resolve the issue by reviewing the BIOS settings of the connected PC.A BIOS is a program that controls and manages parts and equipment used on a PC.However, it is better not to change the BIOS settings except for those who are used to operating devices such as PCs.Expert knowledge is also required, and if the BIOS setting is incorrect or the operation is incorrect, the PC will not boot, and other problems may occur.Use caution when reviewing BIOS settings.If you′re worried or in trouble, don′t force yourself to do it and talk to a professional data recovery company before you regret it.
· Items to be checked in BIOS settings when USB memory is not recognized
①Is USB memory disabled?
②Is it enabled or enabled for items such as USB ports?
*If the USB memory has been disabled after checking the BIOS settings, it cannot be used even if connected to a PC.
·Example of how to start BIOS settings screen
①Press F1 or F2 or DEL keys immediately after the PC is powered on.
②′As soon as the PC is turned on, ′′F1 key′′ is hit continuously.′
*Please refer to the manufacturer′s page and instruction manual as the method of starting the BIOS settings screen varies depending on the model.
·Examples of how to check the USB device settings after starting the BIOS screen
①The BIOS Setup screen appears.
②Check USB items such as USB Port, USB Support, USB Controller, and USB Functions
③′Enabled′ display → mark with settings enabled
④′Disabled′ indication → setting disabled
⑤Change to Enabled if you want USB devices to be available
*If the item の is checked and it says Disabled, the USB memory will not be available.
*In the case of PCs used by enterprises, the setting may be set to Disabled as a security measure.
*Reviewing BIOS settings is an unfamiliar screen with few things to do in the first place, so if you feel a little uneasy or have trouble while working on it, you should give priority to stopping.9. Using Error Checks
If you are using a Windows PC, you may be able to use error checking to automatically repair minor logical failures (e.g., minor bad sectors or file system failures) on your device.
·How to use error checking
①Click Windows System Tools → Select a PC
②Right-click the drive you want to check → Click Properties
③Click the Tools tab → Click Check to check the error
④Scan begins
⑤If an error is detected, a message appears to restart the PC to repair the file system.
⑥System repairs automatically upon reboot
エラーError check cannot repair more than moderate logic failure.
エラーError checking is not available when the device you want to repair has a physical failure.If you use it, it will only make the situation more serious and only show the disadvantages, so don′t try it when you suspect a physical failure or when it′s difficult to determine whether a logical or physical failure is occurring.It is better to avoid doing the operation that would cause problems with USB devices that cannot be recognized to be repaired, but it would lead to the opposite result.
10. Other Solutions
Other workarounds include changing the drive letter or trying the drive when the external hard drive is no longer recognized. Disengaging or stopping the resident program may resolve the issue of USB memory not recognition.

What to be careful about when USB memory is not recognized?
If you experience problems such as USB memory not being recognized or read, please note the following points:
Repeated USB memory insertion and removal is not allowed.
Avoid continuing to energize or restart repeatedly
Bending USB memory is dangerous
Breathing on USB terminals ·No air is allowed to be sent with a dryer
Careful BIOS configuration changes to BIOS settings
without formatting or initializing
1. Repeated USB memory insertion and removal is not allowed.
If you experience symptoms such as USB memory not recognized when connected to your PC, be careful not to rush and reseat it.By repeating, the USB terminal part is heavily loaded. ·The base part of the USB terminal is peeled off. ·The degree of failure and failure deteriorates. ·The stored files and folders are damaged. ·The data often disappears.
2. Avoid continuing to energize or restarting repeatedly
If the PC itself or the connected device fails, it is a priority to turn it off first.If the PC continues to be energized, the program will continue to run even if you are not operating it in the background.Therefore, if you keep USB memory connected to your PC, the data will be overwritten and the situation will get worse.Also, rebooting is one of the most burdensome acts on the equipment.If there is a device that is about to break or is already out of order, you may end up in an irreversible situation as a result of repeated reboots.If you try again and again in the hope that you will be able to recognize it, only the disadvantages will stand out.
3. Bending the USB memory is dangerous
When the USB memory is bent, do not bend or hit it to restore it to its original shape.It can break important parts such as the foundation and lead to cracks.It often causes fatal damage to the location where the data is stored and to the USB terminal for connection.If you think it′s bent, you should consult with the data recovery company without touching it any more.
4.Breathing the USB terminal and sending the wind with a dryer is not allowed.
When the USB memory is not recognized, do not breathe into the USB terminal to remove dirt or dust, or use a dryer to send air when submerged or wet.When dust and dust are accumulated, these actions can lead to deep penetration, and secondary damage such as rusting and deformation due to water penetration into the USB device.USB memory is a small, very delicate recording medium.In particular, it is often dangerous to deal with the problem by yourself when it is submerged with a personal computer, and if you think that data is important or that you will be in trouble if it is lost or cannot be taken out, you should consult a professional immediately.

6. Do not format or initialize
If the USB memory is not recognized, formatting and initialization may bring the USB device back to use, but it is often difficult to resolve the problem, so you should avoid trying it easily.Formatting and initialization work is to restore the equipment to its original factory condition, and if you do, all the data inside will disappear.Be careful not to format data stored in USB memory unless it is unnecessary or completely backed up on other media.If by any chance you format it, you should consult a professional data recovery company immediately.If it was just after the formatting, the data will continue to power up, plug in and out, power off, reboot repeatedly, surf the web while connected to the PC, and the data will continue to be overwritten.In addition to increasing the difficulty of recovering data, the most important thing is to stop and safely remove USB devices when formatting them.
If you want to retrieve data from a USB memory that you don′t recognize,
If you want to retrieve or restore the data contained in the USB memory in the event of a problem that the USB memory does not recognize or does not read, you can do the following:
DATA RESTORATION SOFTWARE UTILIZING METHOD
How to consult with a buyer or manufacturer
How to consult with a data recovery provider?
1. How to use data recovery software
If you need or want to retrieve data from an unrecognized USB memory, you can use software for data recovery.However, only mild logical failures can be soft and recoverable.When symptoms such as not recognizing, not reading, or not responding, USB memory is often physically faulty, and using software not only increases the difficulty of recovery, but it can also lead to a situation where recovery is never possible again.In addition, if you try using the software easily, it will often cause data to be overwritten or corrupted.If the data in the USB memory is important, you want to take it out quickly and cheaply and safely, or you don′t want to fail, you should refrain from using the restoration software.If you really want to use it, consult a professional data recovery company before you try it.
2. How to consult with the purchasing store or manufacturer
If you want the device to work properly or want to repair it rather than the data stored in the USB memory, you can consult with the buyer or manufacturer.The purpose of repair is to return the broken equipment to use again, and it is necessary to be aware that if you consult with the buyer or manufacturer, the equipment will be initialized and all data will disappear, or that it will be replaced with the same product.Please note that the data will not be returned to you.If you want to retrieve any of the USB memory data, you may want to consult a data recovery company first.
3. How to consult with a data recovery company
When problems such as USB memory not recognizing occur, I often panic.If you want to prioritize retrieving the data inside rather than returning the device to work properly, choose a way to consult your data recovery provider.In the event of a failure or failure of recording media such as USB memory, external HDD, SD card, etc., 高度 advanced technical capabilities 深い deep expertise ④ dedicated environment such as clean room 互換 compatible parts are procured.Since it′s close to your home or workplace, you shouldn′t easily choose a vendor just because it′s displayed in the top of the search results.If you want to solve the problem quickly, worry about the cost, don′t want to fail, or want to minimize business problems, it is important to select the first company to request.
· Items you would like to check when selecting a data recovery company
①Do you have advanced technology (AI technology or proprietary technology)?
②Is recovery and work faster?
③Is the restoration fee listed and illustrated on the website?
④Does the organization work in a dedicated environment such as a clean room?
⑤Are security management and confidentiality obligations thorough?
⑥Whether or not there are any restoration results or cases
There are many data recovery companies, but there are significant differences in their technical capabilities and service offerings.By any chance, if you send it to a company without technical capabilities, not only can it not be restored, but the condition may deteriorate.When you want to safely extract important data, it′s important to choose a company with advanced technical skills, expertise and experience.Advanced technology meets all of the items listed in ~ through の, and because of its advanced technology, we can respond quickly and recover data at a low cost.Not only USB memory, but also various recording media have been restored, so I′m relieved.
Summarize - If you are in trouble, stop and contact the restoration company.
If you are experiencing problems such as not recognizing or loading USB memory into your computer, you should stop and contact a professional data recovery company.It is extremely dangerous to try to continue using the equipment in the event of a failure or symptom, repeated insertion and reboot, and continuous energization.Not only does the situation get worse, but it can also happen in many cases where the situation becomes irreversible.USB memory is one of the most delicate devices that can easily impact internal components, such as the foundation, with bare USB terminals to connect to a PC.Physical failures often occur when they are not recognized, so it is important to consult with a company with advanced technology.Advanced technology enables cost-effective data recovery and rapid response.If you are in trouble, why don′t you start with a free consultation?

What is USB Memory?
USB memory is one of the smaller storage media that uses USB connectors to connect to many devices, such as personal computers and smartphones, and to read and write data.It′s small and light, so it′s easy to carry and hand over, and it′s easy to use just by inserting a USB terminal into a personal computer, so it′s also a popular recording medium for many people.Flash memory is used to record data in USB memory for fast processing.USB memory is said to be more shock-resistant than HDD, but it is also not suitable for reading and writing data frequently and storing long-term data, so it is one of the media that should be taken to prevent sudden data loss.
USB Memory Not Recognized Symptom Example
When problems such as USB memory connected to a computer do not recognize or read, the following symptoms often occur.
Error messages such as フォーマットMust be formatted する and アクセスInaccessible 」 appear.
The lamp does not light up when the USB memory is connected to the computer.
USB Memory Does Not Appear in My Computer
1. Error messages such as ′Must be formatted′ and ′Not accessible′ are displayed.
When inserting the USB memory into the computer, it says, ′It needs to be formatted.Do you want to format it?′ There are a lot of problems that can occur.
·Examples of formatting error messages
Error Indication OS
Drive: must be formatted to use .Do you want to format it? Windows 10, 8, 7, Vista
The disk is not formatted.Do you want to format it now? Windows XP
The disk that you set was a disk that this computer could not read. macOS iOS
パソコン The message contents are different depending on the computer model and OS.
When USB memory becomes unrecognized, it should be formatted.Do you want to format it?′ and if you press ′Yes′ in a hurry or format it incorrectly, all data stored in the USB memory will disappear.Formatting refers to restoring equipment to its original factory condition.Formatting solves the problem of logical failures, and the USB memory itself may return to recognition, but in most cases, the problem is not solved, and the disadvantages of data disappearing are more noticeable, so don′t do it.If you format it incorrectly, it is important to remove the USB memory from your computer.If you keep plugging it in or trying to do something about it, the data will continue to be overwritten, and if you remove it from your PC immediately, you will not remove the USB memory from your PC, and if you continue working on it, you will often end up in an unrecoverable situation.Let′s be careful.

·Other examples of error messages displayed when USB memory is not recognized
When USB memory is not recognized, the following message is often displayed on the connected PC.
①inaccessible
②Reconnect the device.
③The USB device is not detected.
④The last USB device connected to this computer is not functioning properly and is not recognized by Windows.
⑤Invalid parameter.
⑥The file or directory is corrupt and cannot be read.
⑦If the device is still not detected, the device may not be functioning properly.
When the USB memory is inserted into the computer or when using it, when some error message is displayed and the USB memory itself becomes unrecognizable, the USB memory itself is on the verge of breaking or has already broken.The condition often deteriorates just by reseating, turning off, or rebooting the USB memory. If you are worried that the data stored in the USB memory is important, missing, or unable to retrieve it, you should remove the USB memory from your PC and try not to get any worse.
2. The lamp does not light up when the USB memory is connected to the computer.
If the USB memory is not detected, check to see if the USB memory lamp in your computer is lit.If the lamp is not lit, it is presumed that the power supply is not working properly.If the power supply is not good and the USB memory lamp does not light up or is not recognized, it may be caused by パソコン malfunction or failure of the computer USB deterioration or damage of the USB port USB damage of the USB hub.
3. USB memory is not displayed in My Computer
There are many cases where USB memory is not displayed in my computer even though the USB memory lamp is lit.This occurs when the computer does not recognize USB memory as a device.If the USB memory is not detected on Explorer or My Computer, USB The USB memory itself is physically faulty or about to break USB The USB port is faulty or damaged デバイス The device driver may be damaged.
What Causes USB Memory Not Recognized?
The following are possible causes of symptoms such as USB memory not being recognized or read.
Bad contact, USB memory not plugged into PC
The USB memory itself is out of order.
USB terminal type is different and size is not correct
a power shortage of electricity
BIOS Configuration Issues
PC malfunction, malfunction, or damage to parts
USB Hub Damage or Defect Occurs
1. Bad contact · USB memory is not firmly inserted into the PC
When symptoms such as USB memory not recognizing occur, the device you want to recognize is often not inserted correctly into your computer or the connection is poor.When using USB memory, make sure that the USB memory terminal is firmly inserted into the USB port or USB connector on the computer side.
2. USB memory itself is faulty
If the USB memory inserted into the PC is not recognized, does not read, or does not respond, the USB memory itself is often broken, so you need to be careful.
①I often use it with my computer plugged in.
②I carried it with my USB memory in my computer.
③I hit and dropped the USB memory against the wall with it in my computer.
④When my computer was submerged, my USB memory got wet.
⑤I had a USB memory in the pencil case, and when I took it out, it was bent.
⑥When I pressed the USB memory hard when it was not detected, it deformed.
⑦USB memory terminal appears to be damaged
There are many cases where USB memory itself is not recognized as a result of a failure.If you have any idea of the items listed above, it is thought that the USB memory itself has failed and you should be careful.After USB memory is no longer recognized, the condition often becomes critical just by reseating, powering on, or rebooting.If the data in the USB memory is important, or if you want to take it out or recover it, you can start by removing it from your computer.Keep using the USB device and don′t touch it even if you want to check the files and folders inside.It is often the case that a recoverable state falls into an unrecoverable state.

How to recover USB memory and restore data | Learn how to deal with each symptom
https://www.adte.jp/rec/hdd/post-953/
USB memory is a small and convenient recording medium for carrying, storing and sharing data.However, since it is small and easy to carry around, it is often shocking, and one day suddenly the USB memory was not recognized or broken, so I accidentally deleted the data.
3. The USB terminal type is different and the size is not right.
There are several types of USB memory terminals.
·Examples of USB memory terminal types
①Type-A
②Type-B
③Type-C
Most USB terminals are Type-A, and Type-A USB ports can only be connected to devices with Type-A USB terminals.Some types of USB memory have Type-C USB terminals instead of Type-A, so let′s check the size.If you can′t connect properly, get dizzy, or are about to come off, it is possible that the USB port has a USB memory with a Type-C terminal in relation to Type-A.
4. Lack of electricity
USB-enabled devices, such as external HDDs, keyboards, and mice, are often powered by a computer.However, connecting such USB devices to a personal computer at the same time may require a lot of power to operate each device, resulting in problems such as USB memory not being recognized or read.Minimize the number of USB devices connected to your computer when you experience symptoms such as not only USB memory but also devices connected to your computer.The situation is often improved by a simple method.
5. BIOS Configuration Issues
The computer contains a program system called BIOS (BIOS) that manages and controls components and connected devices, such as internal components (base/motherboard/storage) and external connections (external HDD/USB memory/keyboard/mouse).If this BIOS setting is changed due to some trouble or the USB device setting is disabled in the BIOS, the USB memory will not be recognized.Let′s check if the BIOS settings are appropriate and there are no problems.
BThe BIOS setting method varies from computer to computer, so you need to look at the manufacturer′s homepage.
6. Computer malfunction, failure, and damage to parts
Problems and failures on the PC and output equipment with USB memory inserted, and contamination, rust, and damage to parts such as USB ports can lead to USB memory not being recognized.If there are multiple USB ports that can connect USB memory, plug it into a port other than the one you always use. If you can use multiple computers, try inserting USB memory into other computers to see if it can be recognized.If the USB memory is not recognized, the problem is often with the computer or the like, not the USB memory side.

What Causes a PC to Break and How to Deal with a Failure?
https://www.adte.jp/rec/hdd/post-1687/
This computer is used in many places such as work, private life, hobbies and schools.You may have thought ′Is your computer broken?′ when you suddenly turned off while using it, your computer couldn′t start, your computer didn′t work with a blue screen or a black screen, and you got an error message.Here are some examples of symptoms and possible causes that occur when a computer fails, such as whether important data is included or whether it should be repaired.
7. Damage or malfunction of USB hub
If it is not recognized when connecting the USB memory using an external USB hub without connecting it directly to the computer, it may be caused by a failure on the external USB hub side or a failure to insert the USB memory correctly into the USB hub.There are three main types of USB hubs, each with a different connection method.
①The type that can be used just by connecting a USB terminal to a PC (bus power)
Many USB memory types are of this type.It will be available after receiving power from the computer.There are many similar types of keyboards and mice.
②The type (self-powered) that allows you to connect an AC adapter to an outlet while connecting to a PC.
Because it can supply power directly from an outlet, it can be used for external HDDs, CD, DVD, BD drives, printers with low power consumption, etc.
③Type with both self power and bus power
It can be used differently depending on the size of the power consumption.
パソコン If the USB memory or external HDD connected to the PC is not recognized, check whether the USB device works or is powered by connecting according to the type.If the USB device is supposed to have power but it doesn′t work, it is estimated that the USB hub is damaged or the USB memory itself that was connected is faulty.
Causes of USB memory failure, physical and logical failures
Symptoms such as USB memory not recognized and suspected equipment failure can be categorized into two categories: physical failure and logical failure.
Physical failure in USB memory
Logical failure in USB memory
1. Physical failure of USB memory
Symptoms such as USB memory not recognized, not read, or not responding are often present, and USB devices are often physically faulty when suspected of failure.A physical failure is a condition in which the equipment itself or the parts inside the data are physically damaged.
·Examples of causes of physical failure of USB memory
Deterioration over time / Overtime of rewriting / Shocked from outside / Submerged / Wet / Dropped / Broken / Broken / Broken / Broken / Left unattended for a long time / Life / Dust accumulated / Broken / Foundation peeled / Rusty / Memory chip damaged etc.
*The flash memory installed in the USB memory will expire depending on the number of times it is used.Due to differences in recording methods, although the upper limit is different, it is generally said that the number of recordings can range from 500 to 100,000.USB memory or SSD is the primary recording medium that uses flash memory.You should also recognize these devices as limited recording media.Please note that frequent reading, writing, video editing, defragmentation, etc. often lead to deterioration of flash memory.Also, if you want to store data for a long time, it may vaporize or disappear when you are not using it, so if you want to store it for a long time, you should also store it on other external HDDs or clouds.
USB In the event of a physical failure of the USB memory, it is difficult for individuals to recover or repair it.Recovering data from flash memory also requires advanced technical skills, deep expertise and experience.By any chance, if you send it to a restoration company without technical capabilities, it may not only be possible to restore it, but it may also worsen the condition.If you have the slightest idea that your USB memory might be out of order, you should give priority to consulting a technically competent data recovery company.
2. Logical failure of USB memory
Logical failure is a condition in which the data, files, and areas that are being managed in USB memory are corrupted memory.
·Examples of causes of logical failure of USB memory
Program problems / Data and system corruption / Software failure / Program file corruption / aging / malfunction / data deletion / virus infection / initialization / format / data read/write / secure removal / USB memory PC suddenly dropped / power outage / lightning strike etc.
·In the event of a logical failure of the USB memory
①No data such as files and folders in USB memory is displayed
②′It needs to be formatted.Do you want to format it?′
③′The file or directory is corrupted and cannot be read.′
④′The parameter is invalid.
Error messages such as are often displayed.
In the event of a logical failure of the USB memory, simply doing what you can, such as reseating the USB terminal, turning it off, and rebooting, can overwrite the data, making it more serious and difficult to recover.If you want to retrieve data or recover it quickly and cheaply, it is important to stop.It is a very dangerous act to work recklessly to do something about it.
Learn what to do if the USB memory is not detected.
If the USB memory connected to the computer is not recognized, please try the following solution.
Visually check the condition
Check USB Memory and PC Connectivity
Checking USB Ports
reseat
reboot
use Device Manager
Reinstall Driver
US>Review BIOS settings
Using Error Checks
Other Workarounds
1. Visually check the condition
If you experience symptoms such as USB memory not recognized or read, start by visually inspecting the USB memory for external damage or scratches.
·Examples of USB memory damage
①be crooked
②rusty
③be piled up with dust and garbage
④be wet
⑤be broken
⑥discolored
Because USB memory is frequently reseated, it is easy to load the USB terminal part, which can cause the USB terminal to bend or peel off the foundation.Also, USB memory is a lightweight and small device, so it is one of the models that often causes problems due to dust and debris sticking to the USB terminal part due to the fact that it was put in the pants pocket without a cover, and carrying it with other things in the brushbox or pouch.First of all, it is important to visually check if there are any abnormalities or damage.
万が一 If by any chance, damage or deformation of the USB memory itself or the USB terminal part can be confirmed by visual inspection, do not try to use it forcibly.It is not only difficult to recover just by reseating and energizing, but it is often impossible to recover.For those who value data or want to recover quickly and cheaply, consult a professional data recovery company immediately.
2. Check the connection between USB memory and PC
If the USB memory connected to your computer is not recognized, check the connection.
①Is the USB memory plugged into the PC properly?
②Is the USB memory lamp on?
③Is the PC receiving power?
④Is there a power shortage?
⑤Is the USB Memory Powered On (Single Power Supply Type)
*If the USB memory is no longer recognized, it is also important to remove all other USB devices connected to the PC once in order to understand the cause.
3. Checking USB Ports
Continuing to use the same USB port may result in poor contact or damage.If you are using a PC with multiple USB ports, connect it to a different USB port to see if the device can detect it.In some cases, only certain USB ports are damaged.If the external USB cable is broken or is likely to be disconnected, you can use a different USB cable to resolve the problem.If you have multiple devices, one of the ways to deal with this is to insert USB memory into another PC and check if it can be recognized.
4. Reseat
If the USB memory connected to the computer is not recognized, try reseating it only once.If it is not inserted correctly or the connection is bad, you can expect to improve the situation by reinserting it.However, you must not try again and again.When the USB memory was inserted into the computer and could not be recognized, the USB memory itself was already broken, the USB terminal was damaged, and the parts inside were often damaged.In such cases, if you repeat the insertion and removal, the condition will become serious, and not only will it increase the difficulty of recovery, but it may also lead to an unrecoverable situation.
5. Restart
When you remove external devices such as external hard drives and USB memory from your computer, you must safely remove them using features such as Safe Removal of Hardware.However, if you remove it without doing this, the communication between the USB memory and the PC will be interrupted in the middle, and the USB memory will not stop working and will be put on hold while the communication continues.If this happens, you will need to restart your computer.Rebooting is an act that puts a heavy load on both PC and USB memory.By any chance, if the USB memory itself is about to break or if it is already out of order, you may end up in an irreversible situation.Let′s reboot only once.If the USB memory is not recognized correctly after restarting the computer, it is estimated that the USB memory itself is faulty, so it is best to contact a professional data recovery company immediately without any unnecessary action.
US>6. Using Device Manager
Device Manager allows you to verify that your computer is able to recognize USB memory.
·How to use Device Manager on a Windows 10 computer
①connect USB memory to a personal computer
②Right-click the Windows mark → Open Device Manager
③Open Disk Drive or Universal Serial Bus Controller
④Check if the USB memory connected to either of の is displayed.
·If the device is not displayed in Device Manager,
①Device Name Does Not Appear in Device Manager
②The device names are marked with ′! Surprise Mark′ or ′? Hatena Mark.′
③USB memory is not displayed in the disk field.
④USB Memory Does Not Appear in Volume List
If you experience symptoms like ~ to の using Device Manager, the connected device is not working properly.·This sign indicates that the PC is not able to load properly load.
デバイス If the USB memory is not displayed in Device Manager, the device itself is often out of order, and it is often impossible to recover just by doing something simple, such as reseating or turning off the power, so try to remove the USB device from your computer.
デバイス If the device is not listed in Device Manager, you may need to reinstall the driver, restore the system, or uninstall updates.However, if you proceed with these operations, you will often lose the stored data, so you need to be careful.Proceed only if you have a pre-backup.If you don′t think you′ve backed up enough or you might not have backed up, don′t push yourself too hard and talk to a professional data recovery company.
′·If ′′Unknown Device′′ is displayed in Device Manager, ′′Unknown Device′′
①Right-click the Windows mark → Open Device Manager
②Remove ′Unknown Device′
上記You may be able to resolve the problem simply by removing the Unknown Device from the above steps.
·Use Disk Management when no problem is found in Device Manager
In Device Manager, you can′t open the files inside even if the USB memory is displayed correctly, and if you don′t have access to data, use Windows′ standard Disk Management feature.Disk Management is a tool that allows you to check the status of your file system.
·How to use Disk Management
①Right-click the Windows mark → Select Disk Management - Windows 10
②Desktop → Move the mouse to the top right → Menu → Settings → Control Panel → System and Security → Administrative Tools → Choose Computer Management (Windows 8/8.1)
·Examples of the display that you would like to be aware of in Disk Management
①′RAW′ appears in the file system field of the USB memory volume.
②Unformatted or Unassigned
③′No Media′ Appears in the Disk Column
①If you see something like ~3, understand it as a sign that the USB memory itself has failed.In this case, if you take unnecessary actions like when USB memory is not displayed in Device Manager, it will not only increase the difficulty of recovery, but you will often end up in an unrecoverable situation, so you should stop touching the device if data is important or you want to take it out.
*By formatting, the USB device itself may be returned to use, but all the data will disappear.Be careful not to format in a hurry.
7. Reinstall Driver
There are two types of USB memory: the type available for drivers that come standard with Windows and the type that doesn′t work without a special driver such as a printer.For USB devices that can be used with standard Windows drivers, the driver will be automatically reinstalled once the driver is removed → connected.If you suspect a driver problem, you may be able to try reinstalling the driver once.
·How to reinstall the driver
①Right-click the Windows mark → Open Device Manager
②Open Universal Serial Bus Controllers and right-click from the list provided.
③Click Uninstall Device or Update Driver Software
④wait a few minutes
⑤Reconnect the USB Memory
⑥Required Drivers Are Automatically Reinstalled
For USB devices that require a dedicated driver rather than a standard driver in Windows, download the driver from the CD-ROM that came with the device or from the manufacturer′s official website.Manual reinstallation of the dedicated driver may also improve the situation.
8. Review BIOS settings
If the USB memory is not detected, you can resolve the issue by reviewing the BIOS settings of the connected PC.A BIOS is a program that controls and manages parts and equipment used on a PC.However, it is better not to change the BIOS settings except for those who are used to operating devices such as PCs.Expert knowledge is also required, and if the BIOS setting is incorrect or the operation is incorrect, the PC will not boot, and other problems may occur.Use caution when reviewing BIOS settings.If you′re worried or in trouble, don′t force yourself to do it and talk to a professional data recovery company before you regret it.
· Items to be checked in BIOS settings when USB memory is not recognized
①Is USB memory disabled?
②Is it enabled or enabled for items such as USB ports?
*If the USB memory has been disabled after checking the BIOS settings, it cannot be used even if connected to a PC.
·Example of how to start BIOS settings screen
①Press F1 or F2 or DEL keys immediately after the PC is powered on.
②′As soon as the PC is turned on, ′′F1 key′′ is hit continuously.′
*Please refer to the manufacturer′s page and instruction manual as the method of starting the BIOS settings screen varies depending on the model.
·Examples of how to check the USB device settings after starting the BIOS screen
①The BIOS Setup screen appears.
②Check USB items such as USB Port, USB Support, USB Controller, and USB Functions
③′Enabled′ display → mark with settings enabled
④′Disabled′ indication → setting disabled
⑤Change to Enabled if you want USB devices to be available
*If the item の is checked and it says Disabled, the USB memory will not be available.
*In the case of PCs used by enterprises, the setting may be set to Disabled as a security measure.
*Reviewing BIOS settings is an unfamiliar screen with few things to do in the first place, so if you feel a little uneasy or have trouble while working on it, you should give priority to stopping.9. Using Error Checks
If you are using a Windows PC, you may be able to use error checking to automatically repair minor logical failures (e.g., minor bad sectors or file system failures) on your device.
·How to use error checking
①Click Windows System Tools → Select a PC
②Right-click the drive you want to check → Click Properties
③Click the Tools tab → Click Check to check the error
④Scan begins
⑤If an error is detected, a message appears to restart the PC to repair the file system.
⑥System repairs automatically upon reboot
エラーError check cannot repair more than moderate logic failure.
エラーError checking is not available when the device you want to repair has a physical failure.If you use it, it will only make the situation more serious and only show the disadvantages, so don′t try it when you suspect a physical failure or when it′s difficult to determine whether a logical or physical failure is occurring.It is better to avoid doing the operation that would cause problems with USB devices that cannot be recognized to be repaired, but it would lead to the opposite result.
10. Other Solutions
Other workarounds include changing the drive letter or trying the drive when the external hard drive is no longer recognized. Disengaging or stopping the resident program may resolve the issue of USB memory not recognition.

What to be careful about when USB memory is not recognized?
If you experience problems such as USB memory not being recognized or read, please note the following points:
Repeated USB memory insertion and removal is not allowed.
Avoid continuing to energize or restart repeatedly
Bending USB memory is dangerous
Breathing on USB terminals ·No air is allowed to be sent with a dryer
Careful BIOS configuration changes to BIOS settings
without formatting or initializing
1. Repeated USB memory insertion and removal is not allowed.
If you experience symptoms such as USB memory not recognized when connected to your PC, be careful not to rush and reseat it.By repeating, the USB terminal part is heavily loaded. ·The base part of the USB terminal is peeled off. ·The degree of failure and failure deteriorates. ·The stored files and folders are damaged. ·The data often disappears.
2. Avoid continuing to energize or restarting repeatedly
If the PC itself or the connected device fails, it is a priority to turn it off first.If the PC continues to be energized, the program will continue to run even if you are not operating it in the background.Therefore, if you keep USB memory connected to your PC, the data will be overwritten and the situation will get worse.Also, rebooting is one of the most burdensome acts on the equipment.If there is a device that is about to break or is already out of order, you may end up in an irreversible situation as a result of repeated reboots.If you try again and again in the hope that you will be able to recognize it, only the disadvantages will stand out.
3. Bending the USB memory is dangerous
When the USB memory is bent, do not bend or hit it to restore it to its original shape.It can break important parts such as the foundation and lead to cracks.It often causes fatal damage to the location where the data is stored and to the USB terminal for connection.If you think it′s bent, you should consult with the data recovery company without touching it any more.
4.Breathing the USB terminal and sending the wind with a dryer is not allowed.
When the USB memory is not recognized, do not breathe into the USB terminal to remove dirt or dust, or use a dryer to send air when submerged or wet.When dust and dust are accumulated, these actions can lead to deep penetration, and secondary damage such as rusting and deformation due to water penetration into the USB device.USB memory is a small, very delicate recording medium.In particular, it is often dangerous to deal with the problem by yourself when it is submerged with a personal computer, and if you think that data is important or that you will be in trouble if it is lost or cannot be taken out, you should consult a professional immediately.
