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.
