RAID Data Recovery Service and Raid Restoration

If you think your RAID array is failing or has gone off line, please use caution! Forcing a RAID array back on-line after a failure is almost never successful and frequently results in the permanent loss of data. Please read our article on RAID backup procedures before forcing an array back on-line and then call Data Recovery Link at 800-625-6451 or 303-649-1181 in Denver. We can recover your data even after other have tried unsuccessfully.

Raid Recovery Information
If you have a RAID Data Recovery please call us at 303-649-1181 for immediate assistance. In order to prevent corruption on your RAID system please read our description of how to back up your RAID. Using the "rebuild" function built into the RAID controller is the number one cause of RAID data being permanently lost or corrupted even though the manufacturer will tell you it is safe. Forcing a RAID back online or doing a rebuild after the array has gone off-line is the main cause of unrecoverable and permanent loss of data. If you would like a free evaluation please call 303-649-1181 for instruction on how to proceed with the RAID data recovery process.

IMPORTANT!
In the event that your RAID is making a clicking, grinding or scraping noise shut it down immediately. Allowing the drives to operate in this condition will likely cause extensive damage to the delicate media housed inside. The longer your drive runs, the less likely your chances of recover.

Self Repair Procedures
If your RAID has crashed or has gone off line PLEASE READ THIS DOCUMENT OR CONTACT US IMMEDIATELY before you try to force the array back on line! We understand RAID data recovery and can help you understand your best course of action in recovering your critical data. In most instances, bringing a failed RAID array back on-line after it has failed will cause permanent corruption of the data.
When a RAID 5 array fails it is almost always due to a multiple drive failure not just a single drive failure. RAID 5 arrays have a built in redundancy that can withstand one drive in the array failing and can continue to operate in a state known as -critical- and can read and write data while in a critical state. Because of this built in redundancy it takes two drives failing to finally take the RAID array off-line completely.
Having two drives that have failed in a single RAID 5 array leaves a critical question. What drive failed first and how long ago did it fail? If the RAID controller has a -force online- function, as most Dell Perc controllers do, then by forcing the wrong drive on-line you will corrupt the array and the data will be lost and not recoverable. If the first drive to fail happened three weeks ago and the second drive failed today then there is a three week difference in the data between the first failed drive and when the RAID failed completely because of the second failure. If you bring the array back on-line or do a rebuild using the drive that failed three weeks ago then all the data on the RAID 5 array that has been created or modified in the last three weeks will become corrupt and permanently lost. For this reason we recommend never bringing a failed array back on-line until you are sure what hard drive failed first and exclude that drive from the rebuild. At DRL we can look at the data using a hex editor and can determine the drive failure order and recover your data. RAID data recovery is a difficult process at best and even the best of data recovery companies have difficulty performing the task with any ease. Using -off the shelf- or -free data recovery software- is not recommended unless the permanent loss of data would be acceptable and can easily be re-created or restored from backup.
We can help determine when it is ok to rebuild the RAID 5 array or to stop and take backup precautions. If you would like to send DRL your failed RAID 5 array, click our -Online Evaluation Form- and follow the instructions. It is extremely important that you do not try to resolve the problem yourself if the data on the RAID 5 array is important to your company and cannot be re-created or restored from backup. The complete and permanent loss of your data can occur faster then you can press the -are you sure- button.
Please contact DRL or read the -RAID Backup Procedures- link to the right for instructions on how to perform drive by drive backups of each drive in the array before you attempt to recover your RAID 5 array.
