I have found a floppy drive lying around. However, as all my computers are connected to the net, I won't be needing it. What would be your recommendations for it, especially if I bump into situations where I may need it to repair really old computers?
I'd say toss it. Pretty much the only reason you'd need a floppy drive in anything that runs a semi modern OS is for inserting drivers into xp (and you are better off slipstreaming drivers).
I have a spare usb floppy drive, but i haven't used it in the 8 years or so i've had it.
The one situation where i see a floppy drive is for installing really old oses without a bootable cd.
