Sometimes there is a pending sector, but it's not user-addressable, sometimes the firmware seems to get the count wrong. You could try doing a full-self-test and see if that terminates without error. If you can temporarily take the drive out of service, you could also try doing a secure erase using hdparm, to see if that gets the count to zero. Tim.
