RAID Data Recovery
We specialize in all types of arrays from RAID 0, RAID 1, RAID 5, RAID 6, RAID 10 and beyond. For more information call: 1-800-717-8974
When you need professional RAID data recovery services, there is only one company to call. ACS
Data Recovery specializes in every RAID configuration, and we can
recover data from any level RAID. It doesn't matter how complex your RAID server might be, we can get your data back. We back our work with a no data - no charge guarantee. We are the only major data recovery company to do this...that is how confident we are in our abilities. We will get your data back, or you pay nothing.
We routinely recover data from some of the complicated systems on the market. Got a failed Hitachi SMS file server? They don't get much more complex than those...14 drives...RAID 6...atypical sector layout. Good luck finding a company that can actually recover data from one of those, but it is something we specialize in. We've even gone so far as to devlop our own in-house software and specially programmed controllers that allow us to recover data where others have failed.
Our recovery process insures that your data is kept safe. We only work from imaged/cloned copies of the original source drives, so that no part of the recover effort will be detrimental to the data.
Although RAID systems increase speed
and are designed to protect your data, on occasion they do fail. If
your RAID system has failed, we can help get your data back. We can
successfully recover data from both spanned and striped configurations,
from RAID 0 to RAID
5 and beyond.
Expedite services are available for all RAID arrays. In
many cases, where a RAID has suffered a logical
or controller failure, we can have your data back to you within 24 hours
of receipt. Additional expedite service fees apply, but when you need
your data back, this is quite possibly the quickest service available
in the industry.

Our RAID recovery methods use a combination of hardware
and software, and we take every precaution to make sure your data is
totally protected. RAID data recovery can be extremely tricky, and before
any recovery method begins, we clone or image each drive sector by sector.
Whatever you do, do not let anyone run any type of recovery tool on
a RAID system. Just one mistake can cause a total loss of your recoverable
data.
Why Choose ACS Data Recovery For RAID Data Recovery?
- All drives are cloned sector-by-sector, so there is no chance
of any additional data loss. We cannot make the situation worse
during our recovery attempt.
- Flat rate pricing (recovery fee based on the total number of drives)
- Specializing in SAN & NAS Equipment
- We can successfully recover data any RAID configuration
- We work with SNAP, HP, Dell, Sun, and many others
- Thousands of satisfied customers
- Expedited Services Available
- Confidential service, and HIPPAA compliant
- We sign confidentiality and non-disclosure agreements whenever
required.
- Recovery lab is biometrically protected to keep your data safe
and secure at all times.
If your RAID has failed, and it contains mission critical
data, you must be extremely careful how you proceed. Running utilities,
replacing drives, and trying to fix the problem yourself can sometimes
have catastrophic results, which may ultimately render your data unrecoverable.
RAID Failure Tips:
- Do not run chkdsk - this will destroy raw recoverable data
- Check all hardware connections
- Check for excessive heat. This causes many hardware failures.
- Clean the system thoroughly, remove all dust build up
- Make sure the drives stay in their original order

What Is RAID?
In computing, a redundant array of independent disks, also known
as redundant array of inexpensive disks (commonly abbreviated RAID)
is a system of using multiple hard drives for sharing or replicating
data among the drives. Depending on the version chosen, the benefit
of RAID is one or more of increased data integrity, fault-tolerance,
throughput or capacity compared to single drives. In its original
implementations (in which it was an abbreviation for "redundant array
of inexpensive disks"), its key advantage was the ability to combine
multiple low-cost devices using older technology into an array that
offered greater capacity, reliability, speed, or a combination of
these things, than was affordably available in a single device using
the newest technology.
RAID configurations are one of the more tricky to recover data from
mainly because your data is spread out among multiple disks which
are typically configured as a single logical unit.
Other RAID Configurations:
RAID 2
Stripes data at the bit (rather than block) level, and uses a Hamming
code for error correction. The disks are synchronized by the controller
to run in perfect tandem. This is the only original level of RAID
that is not currently used. Extremely high data transfer rates are
possible.
RAID 3
Uses byte-level striping with a dedicated parity disk. RAID 3 is
very rare in practice. One of the side effects of RAID 3 is that it
generally cannot service multiple requests simultaneously. This comes
about because any single block of data will by definition be spread
across all members of the set and will reside in the same location,
so any I/O operation requires activity on every disk.
RAID 4
Uses block-level striping with a dedicated parity disk. RAID 4 looks
similar to RAID 3 except that it stripes at the block, rather than
the byte level. This allows each member of the set to act independently
when only a single block is requested. If the disk controller allows
it, a RAID 4 set can service multiple read requests simultaneously.
RAID 6
Extends RAID 5 by adding an additional parity block, thus it uses
block-level striping with two parity blocks distributed across all
member disks. It was not one of the original RAID levels.
RAID 6 is inefficient when used with a small number of drives but
as arrays become bigger and have more drives the loss in storage capacity
becomes less important and the probability of two disks failing at
once becomes greater. RAID 6 provides protection against double disk
failures and failures while a single disk is rebuilding. In the case
where there is only one array it makes more sense than having a "hot
spare" disk.
