I can use dd to put data on a new formatted floppy, but how do I reuse an old floppy. I tried it on linux using dd, but got input/output errors, and even tried it on that other OS, but that couln't complete the format. I even tried reformatting an XP boot floppy on XP, and it couldn't complete the format. I'm a bit lost at the moment. I'd buy some new ones, but my supplier hasn't any available. I know floppies are legacy, but I have an old machine with my smoothwall firewall on it, and it can't boot from cdrom, so I need to remake the 2 floppies that start off the install. Nigel.
