LOL! As if they maintain anything that can read 5.25 in floppies anymore!
I've kept several 5.25" floppy drives from computers I sent to be recycled. I even have a couple double density drive that can only read 320K and 360K floppies. When I was archiving the contents of my floppy disks, I occasionally came across double density disks that could not be read in a high density PC-AT style floppy drive. The only way those disks could be read was to read them in a double density drive. What could really throw them for a loop would be to use 320K (8 sector disks). All versions of Microsoft Windows since Windows 2000 are unable to read them.
