Hi
@T-Bob and all following this post,
I have found that the drive was faulty and the company I brought it off just got a recall notice on them drives as they all need retesting for a hardware fault.
Because of this I have brought 2 new 3TB Toshiba SATA 6GB drives to run in raid a new question have arised to me.
Can drives of the same type be added to the raid at any time if its a master boot with Win 7 OS on it?... "or dose it all have to be configured when the raid is created"
I think 3TB will suit my needs better then the 4TB just for now
