First of all what should I do - is there anyway I can see if the drive has automatic block remapping on? Failing that how do I read the error - what partition is it on? Is there anyway I can track down the file in question? I'm inclined to think its the drive; but the fact that its only happened after its been put on the PC makes me suspicious - even though it is the 3rd one of these drives that we've had!
