2. Summary - In case of trouble
When an error code appears on the TerStation,
If you look at the LCD display when there are some problems or symptoms with the TerStation, you may see an error code starting with ′E′.If you see an error code on your TeraStation LCD display, check the contents first and take action without panic.Some of them are dangerous error codes that are at high risk of losing data.It is also important to stop when you are worried even a little.If you operate or work without knowing it well, the condition will deteriorate, and even if you were able to recover, you may end up in an unrecoverable situation.Let′s be careful.
The contents of the error code starting with ′E′ help you understand the status of the TerStation.
If you see an error code that starts with ′E′, the TerStation itself or internal parts are faulty or defective.
Note that an error code that starts with ′E′ may appear after an information code that starts with ′I′ appears.
NAS conditions as seen by the error code in the TeraStation
The TeraStation liquid crystal display provides an error code that starts with ′E′ to help you understand the state of the TeraStation.Note that not only one error can be displayed, but there are also serious errors and messages that need immediate attention.You should pay particular attention to the error codes shown in red.

AT DATA RECOVERY MEDIUM
What to do when E04 is displayed on the TeraStation?
https://www.adte.jp/rec/hdd/post-2507/
E04 may be displayed when looking at the liquid crystal display when there are problems such as not being able to use TerStation, not being able to stand up, or not starting up.TeraStation is a type of NAS that often stores data in a shared manner, and when problems arise such as not being able to connect, not being able to read data, and not being able to access it, it becomes a problem.Here are some reasons and solutions for E04 on the TerStation.
I get flustered when I see an error code on the TeraStation.In many cases, it is difficult to determine the cause of the error, and there are many cases where data is lost or disappeared due to incorrect operation or failure due to NAS or HDD conditions.If you don′t know the cause or feel a little uneasy, don′t push yourself too hard and give priority to consulting a professional data recovery company on the spot.In addition, TerStation liquid crystal displays may display information codes that begin with ′I′.Sometimes an error code appears after the information code appears, and the information code itself, as well as the error code, requires attention.In particular, I11 (HDx Warning) is a situation where a bad sector on a hard drive, like E15 (HDx Error E15 Many Bad Sectors), is at risk and causing problems, so careful attention is needed.Be careful when the terra station is making noise.This is a sign that the hard drive is seriously faulty.
How to Determine the Error Code Displayed in the TerStation
If there are any problems or problems with the TerStation, you can check the error code by following the steps below.
①press the DISPLAY button
If there is a problem or abnormality in the TeraStation, press the display button to display the error code and check the contents.There is not always one error code or message.There is only one error code message on the LCD display, so press the display button a few times to see if there is anything else.Be careful because multiple errors and failures can occur at the same time.
②Determine the Error Code Displayed
Take notes of the error code that appears on the TeraStation display.Each error code has different troubleshooting and recovery methods.
What do I do when I see an error code on my TeraStation?
If you see an error code on your TeraStation, don′t panic and do what you can.Don′t push yourself too hard when you′re having a little trouble or trouble.If you operate or work without knowing the cause or identification, the condition will deteriorate, and when an error occurs, you may not be able to recover because of the work or operation.If data is important, if you want to reduce recovery costs, or if you want to resolve problems quickly, you should prioritize consulting with a data recovery specialist before proceeding.Unplug the power cord and then reboot the TeraStation only once.
Replace hard drives and rebuild (rebuild) RAID by yourself
perform a firmware update
Clean the TerStation itself and fans
Change the deployment of the TerStation
If you try what you can, but you can′t solve the problem, or if you′re in a bit of trouble or a bit of trouble, or if you′re worried,
1. Unplug the power cord and restart the TerStation only once.
The easiest way to do this is to restart the TeraStation when it displays an error code.If the cause is a minor defect or a system error, a reboot may return the TerStation to normal.However, rebooting is a very heavy NAS activity, such as TerStation.A reboot may worsen the condition of the TerStation or cause the internal hard disk to fail.If the error code is displayed on the TeraStation, there are many cases where it has already failed or is about to fail.In some cases, data cannot be retrieved by rebooting.If your data is important, contact a professional data recovery provider before rebooting.
2. Replace the hard disk and rebuild (rebuild) the RAID by yourself
If one of the multiple integrated hard disks fails, you may be able to resolve the problem by replacing the disk, but at the same time keep in mind that it is dangerous.Most of the hard disks that are built into TeraStation were manufactured at the same time.When one hard disk is broken, the other hard disk is also likely to be broken, and RAID rebuilds (rebuilds) after replacing the hard disk often cause the other hard disk to be completely damaged.It is not recommended to replace the hard disk easily because rebuilds themselves often fail.If the data stored in TeraStation is important, will be in trouble if it disappears, or if you are worried about the work, consult a data recovery specialist before replacing or rebuilding it.If you proceed with the work easily, you may regret it.
3. Update the firmware
If an error code is displayed in the TeraStation, it is estimated that the problem is caused by firmware corruption, abnormalities, or OS failures.While updating the firmware when internal components, such as hard disks, are not out of order, it is unfortunate that updating the firmware can worsen the situation.There is a high risk that the data will disappear if the firmware update fails, and if the hard disk is about to break, the disk will be completely destroyed.If you really want to update your firmware, stop and talk to a professional data recovery company first.
4. Clean the TerStation itself and fans
If there is dust or dust accumulating around the fan, such as when using the TerStation for a long time, there may be problems such as not starting the TerStation and not being able to access the data.Heat is a great enemy of precision instruments.Let′s clean around the fans to see if the trouble is resolved.If cleaning does not solve the problem, consider contacting a specialized data recovery company.

https://www.adte.jp/rec/hdd/post-2223/
In some cases, problems such as suddenly not being able to put in shared folders, not being able to access TerStation, and not being able to move after moving may occur.Management software shows TerStation
5. Change the deployment of the TeraStation
NAS, such as TeraStation, is one of the devices that is prone to high fever because it continues to process large amounts of information.If TerStation is not able to drain heat well, it can cause malfunction or malfunction of parts and hard disks.Check if the exhaust of the TerStation is close to the wall, if there are many things around, and if there is no direct sunlight.You should also try to create an environment where you can set up a TerStation in the coolest possible location and prevent problems from occurring.
6. If you can′t solve the problem even if you try what you can, or if you have any difficulties or worries,
I often get flustered when I see an error code on a TeraStation.In the event of a symptom or failure, it is necessary to understand the cause and take correct action.However, it is often difficult to determine the cause.Continuing to operate and work without knowing it is a lot of risk, and just turning it on and off puts a lot of pressure on the TerStation itself, the board, and the hard disk.If you don′t think too much about what you can do easily, you may end up in an irreversible situation.If the data contained in the TeraStation is important or if you think you need to retrieve it, contact a professional data recovery and repair company first.If you consult earlier, you can prevent the deterioration of your condition, and you can also reduce the recovery fee without losing data and recover the data quickly.
What should not be done when an error code is displayed on the TeraStation?
When an error code is displayed in the TeraStation, the highest priority is not to deteriorate the condition.If you think that the data stored in the TerStation is important or that it will be a problem if it disappears, try to avoid the operations and tasks listed below.
to continue to
cycle power on and off
restart repeatedly
Take the HDD out of the TeraStation and connect it to the PC alone.
Do not replace, reseat, or replace hard disks
RAID rebuild (rebuild) is not allowed
continue to work or operate with an error code displayed
1. Continue to power on 2. Repeat power on and off 3. Repeat reboot
Try not to worsen your condition when you see an error code on your TeraStation.Turning off and restarting the power is one of the things that puts a lot of pressure on the equipment.While rebooting may improve the problem, it is often important to be aware that power cycling and rebooting can not only solve the problem, but can also accelerate the deterioration of the condition.If you have important data stored in a TeraStation, or if you think it would be a problem if it disappeared, turn off the device and contact a professional data recovery company without doing anything.There is also a risk of continuing to energize, so it is important to turn off the power when there is an unusual problem, such as an error code.
4. Take the HDD out of the TeraStation and connect it to the PC alone.
Even if you take the hard drive out of TeraStation and connect it to your computer alone, you won′t be able to see the files, folders, and other data you usually use.NAS, such as TeraStation, has RAID configured on multiple internal HDDs and recognized it as a single drive, and when connected to a PC alone, it can cause system corruption, overwriting, and other new error messages such as ′must be formatted.′By any chance, if you format it, the data will disappear.Connecting to a personal computer alone is a risky act, so let′s not do that.
5. Do not replace, reseat, or change the order of hard disks
NAS, such as TerStation, configures RAID on multiple HDDs and stores data according to algorithms.In addition, RAID is built according to the order of the hard drives, so changing the order of the hard drives can cause the algorithm to become inconsistent, cause data to become unreadable, overwritten, or damage the system itself.Be careful not to replace the hard drive if you receive an error message or if something goes wrong.In addition to replacing the hard drive, replacing or reseating the hard drive is also very dangerous.Replacing or reseating a hard drive when there is an error or problem with the hard drive or RAID configuration can cause a RAID rebuild (rebuild) and cause all data stored in the TerStation to disappear.This is one of the risky activities, so if you really want to replace or replace a hard drive, contact a company that specializes in data recovery first.
6. RAID rebuild (rebuild) is not allowed
If there is an error code in the TeraStation, it is often caused by a failed hard drive or a broken hard drive.Most of the embedded HDDs in TeraStation were manufactured at the same time, and not just one of the hard drives is used when multiple hard drives are RAIDed, and when one hard drive fails, other hard drives are often faulty, faulty, or broken.Rebuilding (rebuilding) a RAID is a very burdensome activity for the hard drive.The hard drive that was about to break during the rebuild will be completely destroyed or will often fail, and if the rebuild stops halfway or fails, the RAID configuration may disappear, or the data stored may disappear or become corrupted.If you really want to rebuild (rebuild) RAID, contact a data recovery specialist before proceeding.7. Continue to work and operate with error code displayed
When the error code is displayed in the TeraStation, it is often dangerous because there has already been a serious failure or damage.If you think about it easily and continue to work or operate it for a while, you might regret it.If the data contained in the TeraStation is important, or if you think it will be a problem if it disappears, the top priority is to stop.Unfortunately, if you continue to work and operate it, it may worsen to the point where it is impossible to recover from what was originally possible.If you′re having trouble getting an error code and you′re having trouble, consider using a free consultation with a data recovery specialist.
How to Choose a Data Recovery Specialist
When the error code is displayed on the TeraStation, I get very anxious and confused.If you do not know which company to consult with or do not know how to choose, pay attention to the following points.
Is it a highly skilled company that has its own technology, AI technology, etc.
Recovery time and speed
Are there any descriptions of the cost, such as the restoration fee plan?
Does the organization have a dedicated environment such as a clean room?
Are information confidentiality obligations and security systems thoroughly managed?
Performance of restoration
If you see an error code on the TeraStation, you want to solve the problem quickly, reduce the cost of recovery, or if the data in the TeraStation is important, or if it is difficult to run out, stop and contact a company specializing in data recovery services.If you contact them earlier, they will lead to the desired result.Advanced technology has AI technology and proprietary technology to help reduce recovery costs and speed recovery.It is safe because it is equipped with a clean room and has a lot of restoration experience, and the confidentiality obligation is thorough.

Summary - In case of trouble
If you see an error code while using TerStation, you should stop and contact a data recovery specialist.It is often dangerous to turn off the power, reboot repeatedly, and continue to operate when the TerStation itself or internal hard drive is failing.It could lead to a case where the condition deteriorates and recovery becomes difficult.Avoid continuous energization.You should also avoid downloading or scanning recovery software to do something by yourself.There are many cases where you regret the overwriting.If you send it to the manufacturer, it will take time, and important work may be delayed during that time.In the event of a problem with a TeraStation, you should consult the data recovery company′s advanced technology.With AI technology and proprietary technology, it can be restored in a short time.If you want to reduce the recovery fee or if data is important, why don′t you start with a free consultation?I′m relieved that I′ve had a lot of experience recovering data from TeraStation.

What to do when E04 is displayed on the TeraStation?
https://www.adte.jp/rec/hdd/post-2507/
E04 may be displayed when looking at the liquid crystal display when there are problems such as not being able to use TerStation, not being able to stand up, or not starting up.TeraStation is a type of NAS that often stores data in a shared manner, and when problems arise such as not being able to connect, not being able to read data, and not being able to access it, it becomes a problem.Here are some reasons and solutions for E04 on the TerStation.
I get flustered when I see an error code on the TeraStation.In many cases, it is difficult to determine the cause of the error, and there are many cases where data is lost or disappeared due to incorrect operation or failure due to NAS or HDD conditions.If you don′t know the cause or feel a little uneasy, don′t push yourself too hard and give priority to consulting a professional data recovery company on the spot.In addition, TerStation liquid crystal displays may display information codes that begin with ′I′.Sometimes an error code appears after the information code appears, and the information code itself, as well as the error code, requires attention.In particular, I11 (HDx Warning) is a situation where a bad sector on a hard drive, like E15 (HDx Error E15 Many Bad Sectors), is at risk and causing problems, so careful attention is needed.Be careful when the terra station is making noise.This is a sign that the hard drive is seriously faulty.
How to Determine the Error Code Displayed in the TerStation
If there are any problems or problems with the TerStation, you can check the error code by following the steps below.
①press the DISPLAY button
If there is a problem or abnormality in the TeraStation, press the display button to display the error code and check the contents.There is not always one error code or message.There is only one error code message on the LCD display, so press the display button a few times to see if there is anything else.Be careful because multiple errors and failures can occur at the same time.
②Determine the Error Code Displayed
Take notes of the error code that appears on the TeraStation display.Each error code has different troubleshooting and recovery methods.
What do I do when I see an error code on my TeraStation?
If you see an error code on your TeraStation, don′t panic and do what you can.Don′t push yourself too hard when you′re having a little trouble or trouble.If you operate or work without knowing the cause or identification, the condition will deteriorate, and when an error occurs, you may not be able to recover because of the work or operation.If data is important, if you want to reduce recovery costs, or if you want to resolve problems quickly, you should prioritize consulting with a data recovery specialist before proceeding.Unplug the power cord and then reboot the TeraStation only once.
Replace hard drives and rebuild (rebuild) RAID by yourself
perform a firmware update
Clean the TerStation itself and fans
Change the deployment of the TerStation
If you try what you can, but you can′t solve the problem, or if you′re in a bit of trouble or a bit of trouble, or if you′re worried,
1. Unplug the power cord and restart the TerStation only once.
The easiest way to do this is to restart the TeraStation when it displays an error code.If the cause is a minor defect or a system error, a reboot may return the TerStation to normal.However, rebooting is a very heavy NAS activity, such as TerStation.A reboot may worsen the condition of the TerStation or cause the internal hard disk to fail.If the error code is displayed on the TeraStation, there are many cases where it has already failed or is about to fail.In some cases, data cannot be retrieved by rebooting.If your data is important, contact a professional data recovery provider before rebooting.
2. Replace the hard disk and rebuild (rebuild) the RAID by yourself
If one of the multiple integrated hard disks fails, you may be able to resolve the problem by replacing the disk, but at the same time keep in mind that it is dangerous.Most of the hard disks that are built into TeraStation were manufactured at the same time.When one hard disk is broken, the other hard disk is also likely to be broken, and RAID rebuilds (rebuilds) after replacing the hard disk often cause the other hard disk to be completely damaged.It is not recommended to replace the hard disk easily because rebuilds themselves often fail.If the data stored in TeraStation is important, will be in trouble if it disappears, or if you are worried about the work, consult a data recovery specialist before replacing or rebuilding it.If you proceed with the work easily, you may regret it.
3. Update the firmware
If an error code is displayed in the TeraStation, it is estimated that the problem is caused by firmware corruption, abnormalities, or OS failures.While updating the firmware when internal components, such as hard disks, are not out of order, it is unfortunate that updating the firmware can worsen the situation.There is a high risk that the data will disappear if the firmware update fails, and if the hard disk is about to break, the disk will be completely destroyed.If you really want to update your firmware, stop and talk to a professional data recovery company first.
4. Clean the TerStation itself and fans
If there is dust or dust accumulating around the fan, such as when using the TerStation for a long time, there may be problems such as not starting the TerStation and not being able to access the data.Heat is a great enemy of precision instruments.Let′s clean around the fans to see if the trouble is resolved.If cleaning does not solve the problem, consider contacting a specialized data recovery company.

In some cases, problems such as suddenly not being able to put in shared folders, not being able to access TerStation, and not being able to move after moving may occur.Management software shows TerStation
5. Change the deployment of the TeraStation
NAS, such as TeraStation, is one of the devices that is prone to high fever because it continues to process large amounts of information.If TerStation is not able to drain heat well, it can cause malfunction or malfunction of parts and hard disks.Check if the exhaust of the TerStation is close to the wall, if there are many things around, and if there is no direct sunlight.You should also try to create an environment where you can set up a TerStation in the coolest possible location and prevent problems from occurring.
6. If you can′t solve the problem even if you try what you can, or if you have any difficulties or worries,
I often get flustered when I see an error code on a TeraStation.In the event of a symptom or failure, it is necessary to understand the cause and take correct action.However, it is often difficult to determine the cause.Continuing to operate and work without knowing it is a lot of risk, and just turning it on and off puts a lot of pressure on the TerStation itself, the board, and the hard disk.If you don′t think too much about what you can do easily, you may end up in an irreversible situation.If the data contained in the TeraStation is important or if you think you need to retrieve it, contact a professional data recovery and repair company first.If you consult earlier, you can prevent the deterioration of your condition, and you can also reduce the recovery fee without losing data and recover the data quickly.
What should not be done when an error code is displayed on the TeraStation?
When an error code is displayed in the TeraStation, the highest priority is not to deteriorate the condition.If you think that the data stored in the TerStation is important or that it will be a problem if it disappears, try to avoid the operations and tasks listed below.
to continue to
cycle power on and off
restart repeatedly
Take the HDD out of the TeraStation and connect it to the PC alone.
Do not replace, reseat, or replace hard disks
RAID rebuild (rebuild) is not allowed
continue to work or operate with an error code displayed
1. Continue to power on 2. Repeat power on and off 3. Repeat reboot
Try not to worsen your condition when you see an error code on your TeraStation.Turning off and restarting the power is one of the things that puts a lot of pressure on the equipment.While rebooting may improve the problem, it is often important to be aware that power cycling and rebooting can not only solve the problem, but can also accelerate the deterioration of the condition.If you have important data stored in a TeraStation, or if you think it would be a problem if it disappeared, turn off the device and contact a professional data recovery company without doing anything.There is also a risk of continuing to energize, so it is important to turn off the power when there is an unusual problem, such as an error code.
4. Take the HDD out of the TeraStation and connect it to the PC alone.
Even if you take the hard drive out of TeraStation and connect it to your computer alone, you won′t be able to see the files, folders, and other data you usually use.NAS, such as TeraStation, has RAID configured on multiple internal HDDs and recognized it as a single drive, and when connected to a PC alone, it can cause system corruption, overwriting, and other new error messages such as ′must be formatted.′By any chance, if you format it, the data will disappear.Connecting to a personal computer alone is a risky act, so let′s not do that.
5. Do not replace, reseat, or change the order of hard disks
NAS, such as TerStation, configures RAID on multiple HDDs and stores data according to algorithms.In addition, RAID is built according to the order of the hard drives, so changing the order of the hard drives can cause the algorithm to become inconsistent, cause data to become unreadable, overwritten, or damage the system itself.Be careful not to replace the hard drive if you receive an error message or if something goes wrong.In addition to replacing the hard drive, replacing or reseating the hard drive is also very dangerous.Replacing or reseating a hard drive when there is an error or problem with the hard drive or RAID configuration can cause a RAID rebuild (rebuild) and cause all data stored in the TerStation to disappear.This is one of the risky activities, so if you really want to replace or replace a hard drive, contact a company that specializes in data recovery first.
6. RAID rebuild (rebuild) is not allowed
If there is an error code in the TeraStation, it is often caused by a failed hard drive or a broken hard drive.Most of the embedded HDDs in TeraStation were manufactured at the same time, and not just one of the hard drives is used when multiple hard drives are RAIDed, and when one hard drive fails, other hard drives are often faulty, faulty, or broken.Rebuilding (rebuilding) a RAID is a very burdensome activity for the hard drive.The hard drive that was about to break during the rebuild will be completely destroyed or will often fail, and if the rebuild stops halfway or fails, the RAID configuration may disappear, or the data stored may disappear or become corrupted.If you really want to rebuild (rebuild) RAID, contact a data recovery specialist before proceeding.7. Continue to work and operate with error code displayed
When the error code is displayed in the TeraStation, it is often dangerous because there has already been a serious failure or damage.If you think about it easily and continue to work or operate it for a while, you might regret it.If the data contained in the TeraStation is important, or if you think it will be a problem if it disappears, the top priority is to stop.Unfortunately, if you continue to work and operate it, it may worsen to the point where it is impossible to recover from what was originally possible.If you′re having trouble getting an error code and you′re having trouble, consider using a free consultation with a data recovery specialist.
How to Choose a Data Recovery Specialist
When the error code is displayed on the TeraStation, I get very anxious and confused.If you do not know which company to consult with or do not know how to choose, pay attention to the following points.
Is it a highly skilled company that has its own technology, AI technology, etc.
Recovery time and speed
Are there any descriptions of the cost, such as the restoration fee plan?
Does the organization have a dedicated environment such as a clean room?
Are information confidentiality obligations and security systems thoroughly managed?
Performance of restoration
If you see an error code on the TeraStation, you want to solve the problem quickly, reduce the cost of recovery, or if the data in the TeraStation is important, or if it is difficult to run out, stop and contact a company specializing in data recovery services.If you contact them earlier, they will lead to the desired result.Advanced technology has AI technology and proprietary technology to help reduce recovery costs and speed recovery.It is safe because it is equipped with a clean room and has a lot of restoration experience, and the confidentiality obligation is thorough.
