Although we have since June 2009 achieved a 100% success rate with RAID recoveries, including arrays that have suffered from RAID rebuild failure, complex or proprietary RAID devices, partial data overwrite, controller failure, firmware update and typical user error, there are times where your storage medium will be beyond recovery.
The following are scenarios where data from a RAID array cannot generally be recovered:
- The terminal failure of more than the maximum number of redundant drives in a RAID array
- Any RAID storage device where the data has been completely overwritten
- Any device that has suffered from intense heat (fire) for too long (although we do often recover fire-damaged drives – the temperature and duration are important factors)
- A RAID 1 array in which a rebuild has taken place, but the array was rebuilt from the blank hard drive
Even if you have been told by another company that your data is not recoverable (and has not failed as a result of any of the above) we would welcome the opportunity to examine it.
We have recovered numerous RAID storage devices previously declared unrecoverable.
