Reparing and recovering a RAID 5 when one or more RAID hard
drives
is
making
a clicking noise, goes offline, fails, or their
status
shows the
RAID
as in degraded mode, requires
specialized training
and equipment.
If you
have already
tried to rebuild your RAID but
still can't access your
data,
you
should stop now. Forcing
a rebuild
will only increase
the odds
that your data
loss is permanent.
Do not try re-order the hard drives in the RAID array
hoping that
swapping
the hard drives around will correct
the problem. This is
especially true when
multiple drives
fail in the RAID. Swapping hard
drives around will only
increase
the risk that the parity and striping
is
overwritten
which then makes it almost
impossible to recover
the data.
Permanent data loss 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.
Regardless of which hard drive brand you own or RAID
configuration you are using, it is just a matter of time
before you will need data
recovery. Hard drive data
recovery for a RAID is required for a
variety
of reasons;
data loss due to
a virus, hard drive recovery
due to
natural disasters, data restoration for physically
damaged
hard
drives,
corrupted
operation system
upgrades have been
known
to cause a
hard drive
failure, formatting of a hard drive,
a hard
drive clicking,
as well as
multiple hard drives failures in a
RAID array.
The safest thing you could do at this point is contact
a RAID recovery
specialist to evaluate the damage
and begin the process to recover
data from the hard
drive. To reduce the chances that your data is
completely lost, you will need professional RAID
recovery services. A
RAID data recovery specialist
should have thorough knowledge of
drive
structures,
MFT mount points, HEX, and offsets to avoid
destroying data
while attempting a recovery.
Common RAID Server Failures And Data Loss Issues |
- Adding incompatible hard drives to the RAID array
- Hardware conflicts with the hard drive and server
- Software corruption to the operating system
- A virus infection, software and operating system upgrades
|
- 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

Formatting a boot drive or
partition
can also damage or
remove striping,
which reduces
the recoverability of
data and
causes permanent loss.
Even if you are using RAID
utilities
or recovery software,
unless you
are experienced
with the nauances
of a
performing a RAID server data
recovery and have sucessfully
restored data or rebuilt arrays,
these RAID repair software
packages can potentially cause
more damage.
