RAID 5 Data Recovery: We Recover Data From Failed and Offline RAID 5 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 RAID 5 data from failed hard drives
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 Advanced Data Recovery can rebuild failed RAID 5 hard drives, repair and recover the data your company needs from damaged and offline RAID 5 volumes. Please call before the damage is too severe and DO NOT restripe or create a new array or volume! Once platters are damaged, striping overwritten or changed completely, and makes it more difficult to rebuild your RAID 5 array and recover the data. In these cases the chances of successfully recovering your data are greatly reduced.
Common Causes for RAID 5 Data Loss...
- 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)
- Your RAID 5 array configuration becomes corrupt or damaged
- Adding incompatible drives
- Hardware conflicts
- Software corruption
- Virus infection, software and operating system upgrades
