Mark Lord's hdparm version 7.3 supports the SCSI to ATA
Translation (SAT) pass-through. So if SAT is supported,
this allows hdparm to access ATA (e.g. SATA disks) and
ATAPI (e.g. cd/dvd drives) devices behind SCSI transports.
Note that the SAT layer may be in the kernel (e.g. libata),
in a HBA's firmware (MPT Fusion SAS HBAs) or external.
Also one of those "SCSI transports" might be SATA.
See http://sourceforge.net/projects/hdparm/
Both sdparm and two utilities in sg3_utils used some
tortured syntax to pipe through ATA IDENTIFY (PACKET)
DEVICE responses to 'hdparm --Istdin' prior to hdparm 7.x .
That, in most cases, should no longer be needed.
