RAID Data Recovery | Hard Drive Recovery
Definition: RAID data recovery is the salvaging of data originally
stored on RAID configured media and which has become corrupt or inaccessible.
Data recovery from RAID systems and Hard Disks:
Recovery of data from a RAID configuration can be a lot trickier than recovery from stand alone
hard disks. RAID 0 and
RAID 1 used together (RAID 0 + 1) and RAID 5 offer the best levels of
protection. Of course with the simplest form of fault tolerance i.e. RAID 1 the second hard disk
mirrors what's on the first one and should one of the hard disks go faulty the other one will
seamlessly take over. In RAID 0 of course there is double the chance of losing your data. You need
only one of the hard disks to go faulty and you won't be able to boot into your operating system.
However, there may be occasions when you need a specialist data recovery service. Instances are when
the power to your hard disk has failed and you are unable to get it to spin. Unless you have an exact
copy of that hard disk and are willing to roll your sleeves up and swap power units/motors on the drives
and willing to take the chance of not mucking it up you would probably want to get a specialist in.
Specialists will also often be able to recover data from
But data recovery doesn't of course only become necessary when there is a hardware fault. You
could have deleted data, erased a file, or cleaned out your old emails. It's surprising what
can actually be recovered from your hard disk or RAID array.
When choosing a RAID Data Recovery firm do choose one that offers a money back guarantee or,
even better, a guarantee that you will not be charged if they aren't able to recover your data.
Some data recovery companies also offer a free trial software that you can download and use to
test your RAID array to see if there is any possibility of recovering data.
It's always good advice of course to
backup, backup and backup.
Plan for disasters rather than let
disasters dictate terms to you.
