Raid Data Recovery
Fast and competitive, less
than the competitor's evaluation fee,
$850 for
3-drive raid.
"Oh, my god, it is
only
quarter of what I paid for an evaluation. Thanks
for your fast and affordable service." A web
host company.
"I am writing to thank you for your work on our Linux RAID5
machine over
the weekend of Oct 20th. It was a very urgent problem for us -
we had a
critical deadline to meet and I am pleased to say that with your
assistance that deadline has now been met. We were very happy with the
service you provided and much appreciate that
you worked over the
weekend for us.
Please pass on my thanks to your engineering team.

time."

Raid Data
Recovery from these Raid
configuration:
- RAID Level 0
(referred to as striping): data is split
across drives.
- RAID Level 1
(referred to as mirroring): 2 hard drives
with redundancy by duplicating all data from
one drive on another drive.
- RAID Level 2,
which uses Hamming error correction codes,
is intended for use with drives which do not
have built-in error detection. All SCSI
drives support built-in error detection, so
this level is of little use when using SCSI
drives.
- RAID Level 3
stripes data at a byte level across several
drives, with parity stored on one drive.
- RAID Level 4
stripes data at a block level across several
drives, with parity stored on one drive.
- RAID Level 5
(referred to as striping with distributed
parity): distributes parity among the
drives.
- RAID Level 6.
- RAID Level 7.
- RAID 0/1 or 10:
Dual level raid, combines multiple mirrored
drives (RAID 1) with data striping (RAID 0)
into a single array.
- RAID 0/3 or 30.
- RAID 0/5 or 50:
Dual level raid, combines multiple RAID 5
sets with data striping (RAID 0).
- RAID 1/5 or 51.

What You Should
Do When Experiencing RAID Data Loss:
Shut down the raid and
send to 1st Data Recovery, why?
- As tempting as it
may sound, attempting a hot swap on a
redundant RAID Server could prove more
disastrous than your current problem.
- Playing around
just makes it worse as raid is very easy to
get corrupted.
- Trust your
important data with 1st Data Recovery 18
years experiences. 1st Data Recovery

get your data recovered quickly and have
your business back and running smoothly.
