RAID failure has been a troublesome issue for users. RAID can fail due to several reasons failed RAID controllers, missing RAID partitions, multiple disk failure, or server crash. But, it is still unknown whether RAID failure can occur due to battery or power issues or not. Those who are having the same question can go through this article. It will help you to perform a RAID Data Recovery during failure scenarios.
Underlying Causes of RAID Failure:
We have come across the following reasons behind a RAID failure:
1. RAID Partition Loss
RAID partition loss leads to a failed RAID in most cases. Whenever a virus or malware makes its way into the RAID system, the RAID partition header gets corrupted. Power surge, bad sector, and software/hardware glitches are other sources of a RAID partition loss.
2. Read Or Write Errors
Frequent read or write errors might occur at the time of transferring or accessing data from a RAID. Such errors often lead to a failed RAID system along with data loss.
3. Corrupted Data
Bads sectors automatically appear on the disk with time and usage of the RAID system. Old RAID drives fail to reallocate bad sectors and lead to RAID failure.
4. RAID Server Crash
A RAID server crashes when the drive fails or something goes wrong with the software or RAID controller.
5. RAID Controller Errors
RAID controller errors pop up when the new hard drive is incorrectly added to the RAID array. Moreover, controller errors appear when the Operating System fails to detect RAID partitions or an error occurs during the rebuild process.
Can Battery or Power Issue Lead to RAID Failure?
It has been evident that sudden power surge or outage affects the RAID and its performance. RAID controllers are responsible for making the RAID work in the desired way. In most cases, RAID controllers stop working with a power outage. As a result, the LED or battery light no longer lits on the back panel. However, a power outage is indirectly responsible for a failed RAID.
Furthermore, a defective battery tends to corrupt the SD card located on the RAID controller. The failed RAID controller during the booting process indicates a defective battery. Whenever the battery fails, you need to manually copy RAID configurations to the new SD card. RAID data recovery becomes essential when the data saved on RAID drives are no longer accessible.
Is it Possible to Prevent RAID Failures?
Both battery and power issues are definitely responsible for a failed RAID system but there are some effective workarounds to prevent it. The primary motive of users is to prevent data loss and inaccessibility during RAID failures. Thus, we have identified the following workarounds:
- Monitor the status of your RAID drives
- Use that RAID type which is mostly resistant to failure.
- Periodically backup data on your personal cloud storage.
- Make sure that the battery is in good condition.
RAID might fail regardless of the number of drives you are adding to the RAID system. Therefore, create a plan of action so that you are prepared to deal with a RAID failure. Use RAID Data Recovery tools in case an unfortunate event takes place. You can also involve a RAID Data Recovery expert for the same.
