Sorry guys, of course i meant 1.44mb but i made a quick error.
Most DOS programs often come with CD-Rom versions or ways to boot them off of USBs or something, like Memtest and other benchmarking utilities.
At the time i am thinking of SpinRite. A tool used to recover and repair damaged sectors of HDDs. AFAIK it doesn't have a CD-ROM version and the only way of running should be the floppy disk. So that leaves me having to buy a floppy disk. And since i thought that like spinrite other programs may have diskette only method of running, i thought maybe i should buy a 10pack just in case. But buying a 10-pack of the first brand i find is not such a good decision if it leaves me having to waste many diskettes.
