10.22.1.8 SCT Status Request
Once an SCT command has been issued, a status is reported in the ATA registers. This status indicates that the
command was accepted or that an error occurred. This ATA status return does not indicate successful completion
of the SCT actions. Some commands can take several minutes or even hours to execute. In this case, the host can
determine execution progress by requesting SCT status.
