    Years ago, I had an internal ATA hard drive and internal SCSI hard drives. They were distinctly different beasts. I have not paid much attention to internal hard drives since then, because so many have got into external hard drives and I just don't see SCSI much, if at all.

    Is is possible for an Ultra ATA drive, circa 2008, to be a SCSI drive at the same time?

    No. Ultra ATA is just IDE operating in DMA mode 2 (33 MB/s), which is a completely different protocol and connector than SCSI.

    Thanks a million.

    I was pretty sure, too but I needed confirmation.

    I have a techie friend who brought up this mystery to me, but I was primarily doing anything techie and internal hard drive related only many years ago. Later projects I have worked on have been with external plug and play hard drives, and laptop work, and of course the dreaded tutoring of new users. :)
