I don’t know if any of you actually use floppies anymore, but in case you do, you may be interested in, a DOS tool (which also works in Windows) which lets you format 1.44MB floppy disks to have a capacity of 1.72MB. It also lets you format disks that have bad sectors right at the start of the disk, which would normally turn them into drinks coasters.
It does actually work – I formatted a rather old floppy with 42k of bad sectors (which were admittedly at the end of the disk) and managed to get 1.70MB of usable space (technically 1.62MB if you count it properly).
Still, I can’t think of the last time I copied files onto a floppy for someone, but if I ever have to then at least I can give them 20% more stuff. Found in today’s Langalist.
