The whole point about pass through is that it is designed to use the existing SCSI infrastructure transparently (hence use SG_IO to send an ATA command to a bridge that understands it---but the key point here is that the device so addressed must understand the opcodes). > the passthru cdb is also not clear enough to me: > according to sat-r06 spec byte 0-2 is scsi, 3-9 are ata, 11 is scsi, yes? Actually, no; byte 0 is the opcode, so you could call that SCSI and byte 11 (or 15) is the control as defined by SAM; the rest all contain SAT specific fields.
