Heh heh.

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.  :)
