Have you tried it with that drive ? That is what I had in mind.

That is just a convenience, to get more onto the floppy.

Yes, that is doable. Dunno if its been done tho, presumably.
You should be able to do it yourself using how its done on a floppy.

Yeah, its quite a bit more difficult.
You dont actually have to boot the CD to install 2K
you can just copy the files to the hard drive manually
and install it from there. Or even install it over the lan.

Its possible to boot 2K from the drive with only 8G initially
visible and have the driver see the full drive once its loaded.
You just have to ensure that what needs to be seen when
access is still being done via the bios is in the 8G thats visible.

Yeah, thats the main downside with
NTFS, the simpler free tools often cant.

Its always possible to get systems like that back if
you are careful about making images over the lan etc.
You may well be able to do a net boot.
In your case it would be simplest to just install the
drive in a system that does have a bootable CD
and image it there in case it all goes pear shaped.

They dont need to understand NTFS
to do that basic bad sector scan type op.

Yes it certainly does. Tho even W98 can do it if you are
careful about the location of the files used during the early
boot phase so they are visible when access is still via the bios.

You can certainly just manually copy the W98
CD to the hard drive and install it from there.

I'd do it with the drive in a desktop system myself.

Yeah, that stuff is doable, just a bit fiddly, but doable.
