RAID Recovery: RAID 3 Data Recovery

Recovering data from RAID 3 Hard Drive Arrays

Because data on a RAID 3 array or volume is typically critical to business continuity, when it becomes inaccessible due to one or more hard drives failing, a bad RAID controller, failed upgrade or damaged striping, it is imperative that you shut the server down and get expert help!

Permanent loss of data often occurs when hard drives are swapped, moved from one position to another or placed in other machines in an attempt to rebuild or repair the RAID 3 array. Formatting a boot drive or partition can also damage or remove striping reducing recoverability of data and causing permanent loss.

The RAID 3 data recovery technicians at Advanced Data Recovery can rebuild failed hard drives, repair damaged RAID volumes and recover data your company needs if you call before the damage is too severe. Once platters are damaged, striping overwritten or changed completely,  the chances of getting your data recovered are slim.

Common RAID 3 Failures And Data Loss Issues
  • Raid controller failure or configuration changed
  • Two or more hard drives fail or go offline
  • Server crashes and won't remount the array or volume(s)
  • Configuration becomes corrupt or damaged
  • Adding incompatible drives
  • Hardware conflicts
  • Software corruption
  • Virus infection, software and operating system upgrades

On a RAID 3 array, the data block is subdivided ("striped") and written on the data disks. Stripe parity is generated on writes, recorded on the parity disk and checked on reads.

RAID Level 3 requires a minimum of 3 drives to implement. RAID 3 is highly efficient and single disk failure affects performance only slightly. In certain instances a RAID 3 array can recover from multiple and simultaneous hard drive failure. It is commonly used for applications with very high throughput, such as video production, live streaming, and video editing. Read and write speed is high.
