Just for historical background, the reason they work(ed) that way, is hdparm was originally written (by me) for testing the new Linux IDE driver subsystem. Well, okay, it *was* "new" back in the mid-90s. :) The -i reported what the device driver probed from the drive at boot time, and -I always interrogated the drive itself, and displayed the raw data exactly as the drive reported it. Thus, for some early drives, the data looked good, and for others it was byte-swapped. Eventually ATA standardization kicked in, and all modern drives now agree on the correct byte-ordering, so I changed -I to give human readable output. :) Cheers
