You could try returning the drive.. I don't know what policies are of 
wherever you bought it from.. However, the Manufacturer probably wont 
consider the drive defective until you run their diagnostic utility on 
it.  That will essentially, low level format the drive, (for all intents 
and purposes, fill it with 0's), which should clear the pending sectors, 
one way or the other. Either the sectors will test ok and the drive 
forget the whole thing ever happened, or they will become 're-allocated' 

Personally, if I couldn't get a replacement from the vendor, I would 
just toss the drive.
