The HPA or DCO on a drive can be cleared. The behavior depends
on what the drive has (HPA, DCO, or both):
HPA only – Clearing a drive with HPA only is a volatile (temporary)
change. The next time the drive's power is disconnected then re-
connected (the next time the drive powers on), the HPA will stay
in-tact.
DCO only – Clearing a drive with DCO only is a destructive
(permanent) change. The DCO and its contents will be non-
recoverable.
HPA and DCO – Clearing a drive with both HPA and DCO is a
destructive (permanent) change to both HPA and DCO. In order
for the DCO to be cleared, the HPA must be permanently removed
first.
