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.
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 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.
- 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
