The way you say that makes me think that it does support at some other
level... hot swap controller? Doesn't match MY hardware. Hot swap
partitions? While I get amusing imaginations of cutting and pasting thin
film off a platter, I guess that's not it either. Media? Unless some hot
swap were to totally duplicate the IDE-FLOPPY code, I don't see that
either.
Actually, I'm almost sure that I have booted a system with a drive in,
unregistered it, swapped it, and reregistered it. Unfortunately that
system is in a closet and hundreds of miles away, so I won't just check
right now. But it was built on a junk 486 just to allow insertion of a
pile of old 360 and 520MB drives which were being backed up to CD without
even checking the contents, just so the drives could be recycled.
Since the project was closed and I got paid, I assume that worked.
Either that or the part-timer who did the work shipped about 70 copies of
the bad music he liked and the client never looked :-(
