A hardware error is defined a non-recoverable hardware failure. The
ASQ decodes to a track following error, which means that the drive
had a problem getting to sector 54062592 and 11308544 in some fashion.
Having accesses to two widely displaced sectors fail with this error
implies that the drive positioning hardware is going bad or the drive
is seeing too much shock or vibration.
