Dell RAID Data Recovery
No One Has More Experience with Dell Servers and Raids
Since 1989 Data Recovery Clinic
Do Not Assume Your Backup Is Good.
NEVER RESTORE A BACKUP TO THE ORIGINAL DRIVES.
Is Your Data Mission Critical. If so we recommend you call and ask questions.
If you are not 150% Sure of the status of your system:
IE:
Have all the drives been online before the failure.
Are any of the drives making noise.
Do you have any sector errors.
Can you get to the logs to see what failed.
Do you know why the drives went off line in the first place.
Are you 150% positive.
Will You Bet Your Business on it…. Because you just might be.
Do Not Assume and Do Not Guess. If you are wrong ………………………
We have seen customers work on there systems and not realize that one of the drives has been offline for some time, bring everything back online or perform a rebuild after getting all working drives back online only to find out they now have garbage in the data files.
Reason: One of the drives is not in sync with the drives that have been working and when the rebuild is preformed or the drives are brought back online they synchronize themselves and start to scrub to correct errors. Problem is they have one drive that was out of sync and can write bad information to the rest.
Not sure what to do or how to know, CALL.
If you can’t answer yes to all of the questions above stop and think before you do anything.
We know from experience.
We do supply Phone Support For Raid Recovery.
Call 347-893-3354 24/7.
Dell raids (PERC} come either built into the motherboard (MLB, main logic board) or are plug in to the PCI slot 32bit , 64bit or PCI-X. I have worked on all series PERC raids.
Raid Failures on: Raid 0, Raid 1, Raid 5, Raid 10, Raid 50, Raid 60
Broken Raid- More than one drive is out on the raid during operation and it fails the raid.
Most times this happens while the raid is in a crippled state and trying to replace the bad drive a good drive is pulled or replaced while the raid is powered off. Both will result in a Failed Raid.
The majority of our work is done directly on Poweredge systems. Our success rate on Snap and PowerVault is nearly 100% as long as the proper steps are taken. Dell support is often too quick to initialize arrays. Please call 1-212-537-0444 for a no obligation quote and action plan.
THIS IS A RECOVERABLE STATE
DRC Clones all drives and work the recovery on our systems guaranteeing no further data loss!
Bad Risk Table or Parity Loss- The risk tables have been over written with a new configuration or the Raid has lost the parity. This usually happens trying to correct the broken raid problem, upgrades, big mistakes or employee sabotage and gets worse trying to correct the problem.

ROM UPGRADES, know as flashing the rom bios on a lot of the PERC raid controllers and others will cause the drives to not be recognized.
This happens due to the changes in the firmware to recognize the partition and will cause partition damage. Replacing the old firmware will not help.
THIS IS A RECOVERABLE STATE
Failed Hard Drives: One or more drives fail on raid at same time.
This is just plain old hard drive failure that must occur at sometime. Sometimes its more than one drive and there comes the problem. The raid can only have one failure unless it’s a mirrored raid.
THIS IS RECOVERABLE ONLY IF ONE OF THE DRIVES IS RECOVERABLE OUT OF THE TWO. ONLY ONE OF THE DRIVES CAN BE FAILED FOR RECOVERY. THE RAID IS BROKEN AT THIS POINT.
By using specialized techniques Data Recovery Clinic can perform a data extraction. The different configurations require different techniques.
