>just to complete the story, SCSI does have ATA command pass through.

Very interesting! I just looked it up - it's the ATA PASS-THROUGH command in the SCSI-ATA Translation (SAT) specification. Someone just told me this is apparently a common way to read SMART data from hard drives in USB enclosures.

>There are SATA drives that understand SCSI over ATAPI albeit in a limited way just to be clear.

I assume you mean hard drives. This is extremely interesting. Can you provide more information? Examples of drives, any links?
