5.1.2 HPA/DCO
This screen shows the HPA (Host Protected Area) size and DCO (Device
Configuration Overlay) size.
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.
You can also set an HPA or DCO on a drive by clicking the
SET HPA/DCO
icon. A
window will appear and the HPA and/or DCO size can be set.
This is a persistent change
and will alter the drive’s total
visible capacity/size.
