RAID 5 Data Recovery

Definition - What does RAID 5 Data Recovery mean?

RAID 5 recovery is the process of recovering and restoring data from a RAID 5 storage architecture.

It is a systematic, step-by-step process that extracts data from a RAID 5 drive, which has a very complex and unique storage mechanism.

Techopedia explains RAID 5 Data Recovery

The RAID 5 recovery process starts with collecting initial data and research about the RAID environment. This includes identifying:

  • Number of disks used
  • Disk sequence
  • Disk block size
  • Offset pattern
  • Type of parity used

Once the data is found and RAID parameters are set, RAID 5 data can be recovered using automated RAID recovery software or through manual recovery means.

The manual RAID 5 recovery process requires the user to find the parity position and rotation of the storage array. The user also needs to know the first disk in the array, block size, offset and a few other array/disk level details. RAID 5 recovery generally requires all or most disks to be present, as parity data is copied in between different RAID drives.
