That should make scrubbing (hopefully) redundant :-) I might at last soon get my new system up and running (got a shop to look at it - dud motherboard :-( Of course it's now out of warranty and my supplier has gone bust, but if the shop say it was dud from the start I might be able to claim something ... But that means I'll have a test system - I've acquired about 6 x 1TB drives - so I shall be playing with some slightly more heavy-duty raid configs :-) Cheers, Wol
