With RAID 1, if both mirrored drives fail, can data still be recovered?
In many situations, data will be recoverable. The quality and integrity of the data recovered will depend on the extent of the damage incurred to each failed storage device. If the mirrored volume was operating properly up to the point of failure, then there should be identical copies of the data on at least two (2) drives which will provide 2 chances to recover the same data.
