RAID Data Recovery: RAID 10 Hard Drive Arrays

RAID Level 10 (1+0) requires a minimum of 2 drives to implement, but more commonly has 4 to take advantage of speed benefits. A RAID 10 is a striped array with segments consisting of RAID 1 arrays and having the same fault tolerance as RAID level 1 plus the overhead fault-tolerance of mirroring. In certain instances a RAID 10 array can recover from multiple and simultaneous hard drive failure. Because of limited scalability and high inherent costs, RAID 10 is typically used in database server applications like an Exchange Server or SQL database server that requires high performance and high fault tolerance levels.

Recovering data from RAID 10 Hard Drive Arrays

Because data on a RAID 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 array. Formatting a boot drive or partition can also damage or remove striping reducing recoverability of data and causing permanent loss. The RAID 10 data recovery technicians at ADR 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 back are slim.

Common RAID 1+0 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
