Thanks for pointing me in the right direction.
Now I have another question.
I have a drive that I vaguely remember having to remap some bad sectors.
After using the SMART ATT command on the drive, I was given a list of information, with Name, Val, Worst, Raw
For Re-allocated Sector count, Val is 100, worst is 100, and Raw is 0
For Re-allocated Event Count Val is 100, worst is 100 and raw is 7
Which if either of these tells me if there are been any sectors allocated, also what do the Val, Worst and Raw Values mean. If there is a document that has information on these, a link would help

, I had a quick look but couldn't see any.
Any help would be appreciated.
