RAID 6 Data Recovery
A RAID 6 array takes the configuration of RAID 5 a step further by utilizing two disks for parity. This
configuration offers high fault tolerance and drive failure tolerance and is commonly used for archiving or data
retention. Though two disks for parity is better than one, the array can still fail, and you will need a
professional data recovery company to prevent critical data loss.
In a RAID 6 array, there must be at least four drives with two parity stripes on each disk. This results in a slower write time, but the redundancy means that the array can withstand two disk failures. After this failure, failed drives must be replaced, but it is during a rebuild that user errors occur. Additionally, parity may not be able to fill all the gaps in storage if more than one drive is missing. Secure Data Recovery has the experience and tools to recover any available files from a failed RAID 6.

Types of RAID Failure
There are several types of failures that a RAID 6 cannot protect itself against, even with added parity. Both
logical and physical failures can occur either through unforeseen circumstances or human error Some of the most
common RAID 6 failures are:
RAID Controller Failure
Hard Disk Drive Overheating
Power Level Failure
Dropping Array or Damaging Drives
Deletion or Overwriting

Our Secure Recovery Process
Your RAID recovery starts when you ship your damaged array to us using one of our over 250 drop-off locations
nationwide or by using one of our FedEx prepaid shipping labels. Our engineers will then complete a diagnostic
evaluation to determine the cause of damage, price point, and estimated turnaround time. After the price is agreed
upon, Secure Data Recovery will not charge you more even if the
requires more work than anticipated.
We begin by repairing the RAID to a temporary working condition in our Class 10 ISO 4 Cleanroom. Engineers then
image the disks in the array and piece together the file structures in the proper order. Once the RAID is
de-striped, we will manually extract data using our proprietary tools. The Secure Data Recovery R&D team constantly
develops new tools and recovery methods for existing and emerging RAID sets.
Secure Data Recovery is the only company to return your files on a FIPS 140-2 Level 3 Validated storage device to
ensure total security for your sensitive files.
What to Do When Your RAID 6 Fails
After recognizing a failure in your RAID array, make note of any error messages that are shown or noises you may
hear before disconnecting the power source. Do not continue to use the array as it will only cause further damage.
Do not attempt to use recovery software as it cannot handle complex RAID damage and won’t fix the root cause of the
