If your home or business relies on a Redundant Array of Inexpensive Disks (RAID) for data storage, it writes information to two or more drives. The first form of RAID storage was RAID 0. If you experience failure, recovery is possible if member disks remain accessible.
What Is RAID 0?
Many organizations have replaced RAID 0 storage with newer systems, but they are still in use. A RAID 0 system splits data into blocks that are written or striped across drives. They work faster than a single drive working alone.
To understand how RAID 0 works, think how long it would take you to write down all the numbers from one to 100. By yourself, you might need a few minutes. However, if you had a friend working with you at the same time, you could split the work. They could write numbers one to 50, and you could complete the other half of the requirement.
The same is true if you’re asked to read back what you’ve written. If you must read all the numbers in sequence, it will take you much longer than if you and your friend both read at the same time. However, if your friend suddenly decides to take his or her list and go home, you’ve lost half the data you need.
RAID 0 provides excellent performance for both reading and writing data. It uses all available storage for data and is a fairly simple system, but if one drive fails, everything is lost. The entire array crashes and leads to data corruption. It is not a good solution for mission-critical data.
Causes of RAID 0 Failure
Several issues might cause RAID 0 array failure:
- If one member disk has sectors go bad, data in those sectors will be inaccessible, causing the drive head to crash and the array to fail.
- If drive heads become damaged, the array will no longer correctly function.
- Firmware corruption or logical issues with file system formatting may cause one of the member disks to fail.
- Corrupted partitions within the array might become unusable.
- A power surge or natural catastrophe might damage components.
- Virus attacks might cause device failure.
Data Recovery RAID 0 Array Failure
If you’ve received notification of RAID 0 failure, you probably experienced that sinking feeling that often accompanies the loss of something valuable. An expert may still be able to recover your data. If your hard drive is only disconnected, power down your computer and reconnect it. When you restart your computer, RAID 0 volume may be restored as normal.
If your hard drive failed, do not attempt to use software for restoration or you might overwrite the data you most want to recover. Instead, turn off your system and call a professional data recovery RAID expert to find out your options.
