SCT Commands
SCT commands provide capabilities not covered in ATA/ATAPI-7 for commands that do not fit the ATA
command delivery model. Some SCT commands report completion when the command begins execution.
Execution progress for these commands may be checked by requesting SCT status. For instance, the host
can track the progress of a Write Same command by issuing a status request once per minute. See ATA8-
ACS for a full description of SCT.
