′I cannot access it.You may not have permissions to use this network resource, and you may lose access to the shared folder with error messages such as ′Access denied′.Here′s how to deal with Windows 10 when you can′t access or connect to shared folders.
3. NAS does not work/start/power on
If the NAS does not start, such as the NAS does not work even though it is powered on or the access lamp does not work, the internal hard drive failure, parts failure, and the NAS itself may be damaged.
4. Error Message Appears
When NAS or shared folders are inaccessible, not only hard drive failures but also OS failures can cause error messages on your computer.
NAS failure point you want to check
In the event of any of the above problems with the NAS, let′s check where the problem is.
1. Hard drive failure
2. NAS body failure
3. Faulty OS part
1. Hard drive failure
When the NAS does not boot or cannot access shared folders, it is often due to internal hard drive or component failure.To determine if the hard drive has failed, check for error messages, error codes, and differences in the light of the access lamp.Also, be extra careful when the hard drive is making noise.
2. NAS body failure
NAS consists of a variety of components, including CPU and motherboard infrastructure and memory, USB, cooling fans, RAID controllers, and HDDs.If a physical part or hard drive fails, repair or replacement will be required.However, repairing parts requires specialized skills and deep knowledge.Also, the parts themselves are not general-purpose, and it is often difficult to obtain the same parts as the broken parts, so they cannot be easily replaced.Also, if the RAID controller or foundation fails, you may be able to check the data by taking out the internal hard drive and connecting it directly to the PC, but if you are worried about machine knowledge or work, you should not move it.
3. Faulty OS part
If there is a problem with the operating system installed in the equipment, it will not boot.Let′s use the management software of each manufacturer to check for problems with the OS.You can check the error information and contents.
Management Software Example

If you have trouble accessing, connecting, or not booting the NAS, the hard drive or the main unit is often faulty, but if there are no problems with either of them, consider the OS failure.When the hard disk is not broken, sometimes a firmware update can resolve the problem.However, it is important to be careful because updating the firmware may cause data to be overwritten and the situation to deteriorate.

What to do when you cannot connect to LANDISK?
https://www.adte.jp/rec/hdd/post-1162/
Many people use I-ODATA-made LANDISK (landisk) to share data within the company′s department or home.NAS such as LANDISK can be used from different devices such as PCs, tablets, smartphones, folders and files at the same time.
What to do in case of trouble?
1. Try what you can do yourself
2. Contact manufacturers and purchasing stores
3. Consult with a data recovery company
1. Try what you can do yourself
①Powering Off
An easy-to-try solution in the event of equipment problems is to turn the equipment off and back on.The symptoms may be improved by turning off the power.If you have a hard drive failure error or are making noise, be careful not to do so many times if your data is important.
②Use the ′S.M.A.R.T.′ feature on the hard drive to determine health
S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology/Self-Monitoring Analysis and Reporting Technology) is a feature that enables early detection of failures and prediction of failures in HDDs and SSDs.This feature provides numerical insight into the state of the hard disk.Software is required to view S.M.A.R.T. information.
·Examples of tools for using S.M.A.R.T.
If diagnostic tools by manufacturer are not available, the following are the main diagnostic tools:Some hard drives do not have this S.M.A.R.T. feature.
Diagnostic Tool Example OS Example
CrystalDiskInfo, Active SMART, From HDD to SSD, HDD Health, Hard Drive Inspector, HDD-SCAN, HDD Life, HDD SMART Analyzer, HD Tune, Mam′s S.M.A.R.T Reader, Hard Disk, Smart Checker, PC-Doctor for Windows, SpeedFan, SMARTRporter Apple Macintosh, Windows Tools, Apple Protoothool, Windows Protoothool, Windows 8
After reviewing the S.M.A.R.T. information, don′t force yourself to continue using it if something goes wrong or you feel uneasy about your work.Also, when connecting the built-in hard disk directly to the computer, it is necessary to format it.Do you want to format it?If you format or change the partition here, you may find it difficult to recover the data, so be careful.Do you want to format it into a computer?When a pop-up appears, it is important to press the cancel button without panic.
2. Contact manufacturers and purchasing stores
If you ask the manufacturer or the buyer for repair, you need to be careful because the stored data will not be covered by the warranty.The hard drive is also replaceable, not repaired, so the hard drive containing the data will replace the new hard drive with no data.Also, if you replace it or repair it yourself, it may not be covered by the manufacturer′s warranty.If you have important data stored on your device, you should prioritize consulting with a data recovery company.3. Consult with a data recovery company
It is often difficult to determine the cause of the failure and to respond to the RAID equipment.Stored data is important.If you′re having trouble with your NAS, not just one person, contact your data recovery provider.Consulting while you′re worried will reduce the time and burden of your work.
Differences Between Repair and Data Recovery
·What is repair?
Repair is to make parts that are broken or malfunctioned, such as repair work or parts replacement, so that they can be used/operated again.In the case of manufacturer repair, the purpose is to restore the equipment to the original condition when it was purchased and to fix the equipment so that it can operate properly.So basically, the stored data is erased by initialization and so on, and then disappears.Some manufacturers need to agree to initialize the stored data when they submit repairs.Be sure to check before you take out the equipment.
·What is data recovery?
Data recovery is a service that retrieves and rescues data from a hard disk or USB memory that is not recognized, a computer that does not boot, a NAS or a server that cannot be accessed, and other media that is experiencing problems.
·Data recovery service flow
①Decompose NAS/Remove Hard Drive in Cleanroom
②Diagnose Hard Drive Failure
③Work and parts replacement tailored to failure conditions with expertise and deep knowledge
④If multiple hard drives are configured for RAID, work specifically for RAID environments
⑤Transfer recovered data to the hard drive
Things you shouldn′t do in the event of trouble - Things you should be careful about.
1. Do not power cycle or reboot repeatedly (it may worsen if the hard drive fails).
2. Do not press the reset button (because it is not a button that can solve the problem).
3. Use free software carefully (be careful as it may be overwritten)
4. Do not format incorrectly (to prevent data from disappearing)
5. Do not tear down or open the hard drive outside of the clean room (dust and dust can cause fatal damage to the hard drive).
Key RAID Types Used by NAS
The main types of RAID used in NAS are:RAID refers to Redundant Array of Inexpensive Disks (Redundant Array of Inexpensive Disks) as raid and is a combination of hard disks and SSDs that can be recognized and displayed as a single drive.
RAID 0 (striping)
