First : if your drive has more than 126 bad sectors as supplied, you
should be throwing it through your vendor's window, not politely asking
for a replacement.
 
If the drive is halfway decent, it probably also has bad sector forwarding,
so you may have several hundred more bad sectors than you think.

A drive with more than a few bad sectors is probably on the way out anyway,
so I wouldn't be trusting it to begin with.

If you _must_ use this drive, look at badsect(8) and see if you can pull 
things off with that.
