Disk vendors already maintain enough spare capacity so that the drive can transparently provide defect management for a few hundred thousand bad sectors without having to report that it's smaller. If the device reports a smaller capacity than sold originally, short of things like HPA or DCO, it has likely exhausted its spare pool, and it's time to RMA the drive with some urgency. -- Eric D.
