"Floppy Disk Formats That Are Supported in Windows XP"
. 1.44 megabyte (MB) 3.5" floppy disk (read, write, format)
. 720 kilobyte (KB) 3.5" floppy disk (read, write only)
. 1.2MB 5.25" floppy disk (read, write only)
. 360KB 5.25" floppy disk (read, write only)
I've not used any sort of 5 1/4" drive under XP, but Microsoft claims that
they're supported.
I think that the floppy controller on a PC of recent manufacture may not
support more than a single drive. Going back to ME wouldn't help that. The
obvious solution would be to obtain an old single drive (eBay)? but I've not
done it myself. That assumes that there's no simple modification to the
3.5"/5.25" dual drive to make it behave like a single 5.25" one.
I'd refer the original poster to Dell support, but I'd be surprised if they
could come up with information of that nature. The demand for getting data
off 5 1/4" floppies must be rather, er, limited in 2006.
