Raid Data Recovery:Our Raid Engineers are highly qualified in the art of extracting data from a failed Raid Array. Emergency service is available 24/7 by calling 800-432-8291 (Toll Free) or direct for international callers +1 201-261-2312
Procedures: (the full service)
- Duplicate as many hard drives as possible.
- Determine the Raid failure and formulate a Data Recovery Strategy.
- If hard drive failures are detected, recover a mirror image of each failed hard drive.
- Determine the hard drive order and the stripe size of the Raid Array.
- Attempt to restore the raid adapter with the recovered hard drives.
- If the raid adapter cannot be restored, reconstruct the Raid image from the raw hard drives
- Return the Repaired Raid to the customer or provide the data on an appropriate destination media.
Other Procedures: (the cut rate service…NOT our method)
- Try to force the failed elements back online.
- No hard drive duplication.
- Attempt a raid rebuild without backup.This procedure can create permanent damage to the Raid Array if the Rebuild fails.
- Rely on luck that might work occasionally, but not always.
Raid Data Recovery Services: Raid FailureRaid Servers can fail for a number of reasons:
- On Raid 5 or Raid 10 server, at least two hard drive elements must fail to take the Raid Array OFFLINE.Most commonly, a first hard drive failure occurs at some point and is unnoticed, ignored or a replacement hard drive has been ordered but is not yet installed.
A second hard drive (member Raid Element) develops a problem. Even a minor problem such as a few bad sectors can cause the Raid Array to crash
Thus the reliability of a well maintained Raid 5 system is fairly good.
- On a Raid 1 Array, just one hard drive malfunction can cause a crash.This is the worst of all Raid configuration. It has 2^N drives probability of failure, so that a 4 250GB hard drive Raid 0 has a 16X greater failure rate than a single 1TB hard drive. Most people don’t even know they have a Raid 0 storage because it’s in a sealed box, when they find out, it’s too late.
- Raid Controllers can fail.Raid controllers can also fail or lose their configuration settings. Power surges or power failures can cause problems especially if you don’t have a UPS (uninterruptible power supply) or even if you have a UPS, if the battery runs out and you have no automatic shutdown procedure setup.
- Other Hardware failure.Many other electronic parts in a server can fail but usually can be replaced without affecting the Raid Array. The worst minor defect that I have seen was a 25 cent molex drive power connector, 2 had failed intermittently eventually causing the Raid to crash.
