5.0.3.2 HPA/DCO/TRIM
HPA and DCO is a setting that can be found in Drive to Drive and
Drive to File. Some computer manufacturers will use a utility
that creates an HPA or DCO configuration on a hard drive. These
configurations are designed to change drive characteristics such
as drive capacity, speed and other settings as they are reported
to the computer’s BIOS.
The HPA/DCO setting allows the user to set whether a drive’s
HPA or DCO is to be unlocked and imaged. Select YES to unlock
and image a Host Protected Area (HPA) or Device Configuration
Overlay (DCO).
HPA – Host Protected Area can limit the size of a hard drive, but
it can also change many other settings such as speed and

100GB drive to a computer.
