Ofcourse, but is the head actually sensitive enough to be able to cooperate with this? Professional data recovery companies actually take out the platters and use their own drive-heads to get the data out. > There is some doubt as to whether spinrite can even function in this wise > with modern drives though. Yes, and that's exactly my point. Something that overrides the drives firmware can, in my view, easily brick the drive. -- Joost
