RAID Data Recovery: RAID 5 Hard Drive Arrays

Each entire data block is written on a data disk; parity for blocks in the same rank is generated on writes, recorded in a distributed location and checked on reads.

RAID Level 5 requires a minimum of 3 drives to implement. It is the most versatile array design, and is used for databases, mail servers, file servers, etc. A RAID 5 is a striped array with segments consisting of RAID 5 arrays and has the highest data reading speed of RAID models. In certain instances a RAID 5 array can recover from multiple and simultaneous hard drive failure.

Recovering data from RAID 5 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! RAID 5 has the most complicated controller design and is difficult to rebuild in the case of a failure.

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 5 data recovery technicians at American Data Recovery, Inc. 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.
