I jsut got a 1040 and it came with some floppies but some don't work. Does anyone know if they can be fixed or is it hopeless?
This is the problem with an ancient magnetic storage medium. Assuming the best-case scenario, which is that it's the disks at fault rather than the disk drive, the chances of you fixing those disks are not good - basically, ones have become zeros and vice versa. This is why I was harping on about CF adapters in the other thread. Floppy disks are a nightmare.
Fixing what? The data or the disk? Neither have much chance of recovery if they're damaged. You might want to try a floppy head cleaner for the drive, but I wouldn't hold out much hope.
Unless there was something unique on the floppies, don't spend time on them. Everything Atari is dumped, so get a clean copy of whatever it was from the dark reaches of the net and rewrite it on a fresh floppy.
It's ordinary PC DD floppies, so it's not hard to find more blanks or get a bunch or used ones you can reformat. Same thing for Amiga: Ordinary DD (or more rarey HD) floppies.
And you can format HD disks as DD ones...because let's face it, you're not gonna find new DD disks any time soon.
