About RAID 0 failure
Array corruption tends to be more dependent on the number of drives installed. But that’s not the only reason disks can become unusable; other things can provoke RAID 0 failure, including:
- Damage to one of the sections of the array. When the array is divided into partitions and one of them fails, the work will stall until you rebuild the array again.
- Viruses and malware. Even the highest quality antivirus application will not give you a 100% guarantee against viruses and worms. They can get to important system files, which in turn will lead to a malfunction of the entire array.
- Defective or broken controller. The controller in the array needs special attention since it manages all the connected drives, carries all the configurations, and more. Therefore, it can very much affect the whole RAID 0. Sometimes its replacement will even be better than a repair since that will be more reliable.
- Broken head on the hard drive. In fact, if the head is out of order, it is not possible to write information to the disk or do anything else on the disk. If so, then your hard drive needs to be repaired or replaced with a new one.
- Bad sectors on the disk. These must be eliminated immediately since sooner or later they can lead to data loss.
- If one disk in the array is not working, then it will simply fail. Therefore, you need to constantly monitor the operation of each disk in the array and, if you suspect failure, take appropriate preventive measures. Only in this way will you be sure of your RAID 0’s performance.
What you can do if RAID 0 drive failure happens
If you have the RAID failure due to disconnect of a hard disk, you can use this method:
Access your disk and reconnect the disk. Naturally, all this must be done with the computer disconnected from the network. It is also recommended to check all wire connections.
How to recover files from RAID 0
Ideally, you will have created a disk image and only then would you try to recover the data. You can handle both data recovery and disk image creation with the help of one professional software tool: DiskInternals RAID Recovery. It recovers files from an array or from a disk image.
The software independently determines the numbering of disks, RAID configuration, lane size, etc.
Check out the detailed guide for DiskInternals RAID Recovery:
After downloading and installing RAID Recovery, select the required array for recovery.
Decide on the scanning method:
- fast scanning
- deep scanning
The software will examine the current state of the array controller, the array itself and its disks, and the file system. Then, file recovery takes place where possible.
After viewing the data found, buy a license, which will let you export data to any external storage device.
