Repeat as needed. I would NOT recommend it at the moment - it's untested and reputedly breaks raids 5 & 6, but look at dm-integrity. If we could trust it, it would be a wonderful tool with ddrescue. Hopefully I'm about to have a wonderful system with 6 or so drives I can play with as a raid test-bed, and I'm hoping to do a load of work on this. Cheers, Wol
