9.18.2.3 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.
Log page E0h contains the status information. Reading log page E0h retrieves the status information. The SCT
status may be acquired any time that the host is allowing to send a command to the device. This command will
not change the power state of the drive, nor terminate any background activity, including any SCT command in
progress.
