Is this the same as RAID 6, or is this a modficataion of RAID 4 (but with two dedicated parity disks instead of just one)? Thanks! -- richard "Steven M.

If you do have a hot spare, then it should have kicked in when the previous drive failed, and you would currently not be seeing any rebuilds with the drive you already replaced...
