RAID 1 Data Recovery
RAID Level 1 requires a minimum of 2 drives to implement. For highest performance, the controller must be able to perform two concurrent separate reads per mirrored pair or two duplicate writes per mirrored pair. In certain instances a RAID 1 array can recover from multiple and simultaneous hard drive failure. It also uses the simplest storage design. The overhead is very high at 100%, so RAID 1 may not be ideal for a larger server.
Recovering data from RAID 1 Volumes
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 1 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 back are slim.Common RAID 1 Failures And Data Loss Issues
