Reasons for RAID Failure | DataRecovery.org

COMMON REASONS FOR RAID FAILURE

RAID failure occurs due to various reasons and usually falls in one of two categories: hardware failure or software failure.

Common reasons for RAID hardware failure include a problem with one or more drives in the array, controller failure, abrupt power failure or network malfunction. Reasons for RAID software failure include anything from a
virus attack to an operating system malfunction. There are many "quick fixes" typically used by clients attempting to restore a failed RAID that actually cause more harm than good. Such techniques can result in disruption of logical volumes which can destroy the RAID array.

MISTAKES PEOPLE MAKE TRYING TO
RECOVER A RAID ARRAY

Warning: Attempting to recover a RAID array using any of the
methods below can result in permanent data loss and damage
to the RAID array making data recovery more difficult.

OPERATING SYSTEM RELOAD
REBUILD RAID DRIVES
RUNNING THE CHECKDISK UTILITY
RECONFIGURE THE RAID ARRAY
USING DATA RECOVERY SOFTWARE
REINITIALIZE RAID ARRAY
REFORMAT DRIVES IN THE ARRAY

RAID data recovery is an extremely complex type of recovery
that requires much experience and expertise with how RAID
arrays work. If you have a RAID failure, it is best if you do not
try to recover the RAID yourself using "quick fix" techniques or
"off-the-shelf" data recovery software. Contact a data recovery company as quickly as possible. These companies have the capability to recover RAID arrays with advanced recovery tools
and techniques required to ensure a successful recovery.

The success of RAID recovery depends on the cause of RAID
failure, the configuration of the RAID array, and whether or
not the user has made attempts to recover the RAID. Such
attempts can cause permanent data loss!

By using caution and the tips above, you can be on the road to
a successful recovery of your RAID array.
