I am trying to determine if a particular hard disk drive supports hardware-based full disk encryption. I know I can use the model number and check the manufacturer's website, but that is only feasible if I were doing this for a handful of computers. I have a fleet of about 1000 computers that I want to check for this.
Is there some utility or script that I can run on a remote computer that will query a hard disk drive and find out whether it supports hardware-based full disk encryption? What are some effective hard disk interrogation tactics?
I spent some time searching for a way to do this, but I ended up in a dark alley hearing whispers of IOCTL_ATA_PASS_THROUGH and got scared away.
The vast majority of computers I would like to check are running Windows (XP, Vista, and 7), but I do have several Mac OS X computers that I would like to check, too.
