Data Clinic's worldwide
RAID Data Recovery Services
We recover data from
- ANY type of RAID (RAID 5, RAID 0, RAID 1, RAID
6 etc.)
- ANY OS (Windows, Mac, all Linux)
- ANY type of machine - eg. Dell, HP, IBM, Supermicro,
custom systems
- Onsite and Offsite ANYWHERE in the UK
- International service available
 Our RAID data recovery &
repair capabilities are the finest in the country.
We have recovered data from many RAID servers that other data recovery
companies could not.
If your RAID data is valuable please speak to us !!!
Specific failures on RAID systems that we can recover data from include:
- RAID array / Controller Card Failure
- Controller Card Set-up Corruption
- RAID Container Crash
- Server won't boot
- Server registry configuration lost
- Rebuild failure
- Damaged striping
- Multiple hard disk drive failure (or multiple drives go offline)
- Intermittent drive failure resulting in configuration corruption
- RAID array or volumes that won't mount after a server crash
- Configuration damage or corruption
- Addition of incompatible drives
- Hardware conflicts
- Software corruption
- Software or operating system upgrades
Data Clinic's Recovery Process for Servers, NAS, or RAID Arrays
-
Our technicians treat Server and RAID data loss situations as
high priority cases. An initial diagnosis determines whether each
media device is accessible to our lab equipment. If so, the first
priority is to create a raw image of all data from accessible
media onto new media so that logical analysis can determine the
nature of the information loss situation
-
Recovery
of crashed RAID and other hard disks often involves replacing failed
or damaged components in a clean environment and using specialized
hardware and software tools to create the raw image. Failed components
typically include electronics, read/write heads, head assemblies,
magnets & drive motors.
-
Multiple-drive
servers are typically 'destriped' onto our media so that filesystem
repairs can be performed and the data files extracted. Sometimes
the existing filesystem structures are missing or damaged so much
that data has to be extracted directly from one or more fragments
of the destriped image.
-
Our
programmers have created a full set of software tools used by our
technicians to analyze, destripe, fix & recover data from raw
images drives to virtually all operating systems. Once a recovery
has been successfully performed, file lists are created and information
validity is checked.

"Data
Clinic's achievements in the field of data recovery consistently
break new ground and move the industry forward"
Dr P Nutter

"Thank you Data Clinic for the excellent
service you provided in restoring all of the data from the RAID
drives. Although the solutions that Data Clinic provide are clinical
in nature, the people are professional, friendly and bend over
backwards to get the job done. Highly recommended."
C Russell, Digital Asset Solutions |

"I found Dataclinic to be
highly efficient, professional, and gave great customer service.
Within 36 hours of a system failure we had our data recovered
from the server, restored and installed. This was despite the
geographic issue of being some 270 miles between ourselves and
DataClinic, and the fact that the server was shipped back on a
Friday afternoon. Excellent service."

RAID-0
Level 0 is not redundant, hence does not truly
fit the "R.A.I.D." acronym. In level 0, information
is split across drives, resulting in higher data throughput.
Since no redundant information is stored, performance is very
good, but the failure of any disk in the array results in
information loss. This level is commonly referred to as striping.
RAID-1
Level 1 provides redundancy by writing all
information to two or more drives. The performance of a level
1 array tends to be faster on reads and slower on writes compared
to a single drive, but if either drive fails, no information
is lost. This is a good entry-level redundant system, since
only two drives are required; however, since one drive is
used to store a duplicate of the other, the cost per megabyte
is high. This level is commonly referred to as mirroring.
RAID-5
Level 5 employs a combination of striping and
parity checking. The use of parity checking provides redundancy
without the overhead of having to double disk capacity. Simply
put, parity checking involves determining whether each given
block has an odd or even value. These values are summed across
the stripe sets to obtain a parity value. With this parity
value, the contents of a failed drive can easily be determined
and rebuilt on a spare drive.
