I think most drives hide that info, although the manufacturers probably have 
diagnostics that can get to it.
I think you are looking for something similar to what you you did with the old 
MFM drives when you entered the bad block table in at format time. Smart 
utilities usually can only tell you how many spares are used and how many are 
left, or just if there are more bad sectors than the drive had spares for. 
Once that happens, it is time to go drive shopping, and do a full backup 
(backup first I would say).
The modern controllers shouldn't have bad blocks mapped to usable sectors 
unless the drive is heading to the great e-waste box in the sky.
