DESCRIPTION
In some cases, this function translates SCSI commands into ATA taskfiles, and queues the taskfiles to be sent to hardware. In other cases,
this function simulates a SCSI device by evaluating and responding to certain SCSI commands. This creates the overall effect of ATA and
ATAPI devices appearing as SCSI devices.
