Tableau TX1, User Manual

Page: 100 / 125

Note: The TX1 will not allow any other jobs to be started or queued when an IDE
drive HPA/DCO disable job is in progress. This includes disallowing the Shelve
DCO feature for Duplicate jobs. This is because a system reset will be required to
redetect the drive after the DCO is disabled, which would terminate any other jobs
in progress.
4. After the TX1 has booted to the Home screen and the IDE drive is detected, navigate to
the Sources drive list and tap on the IDE drive tile to open its drive details screen.
5. Select the HPA/DCO Disable media utility, optionally enter case information, and then tap
the REMOVE HPA/DCO button to start the operation. The system reset will occur imme-
diately after the TX1 issues the removal commands to the drive.
The log will reflect successful completion of the DCO disable operation after the command has
been issued to the drive, before the system reset has occurred. The TX1 has no way of
knowing if the command actually completed at the drive level. The DCO state should be
manually verified after the reboot is complete and before subsequent jobs are started.
The TX1 also provides the ability to “shelve” a DCO, which means temporarily disabling a
source drive DCO for the purposes of evidence duplication and then putting the same DCO
back after the job is complete. See the
Duplicating section of this user guide for more details
on shelving a DCO.
Blank Checking
The Blank Check utility checks a drive for the presence of meaningful data.
