formatting and checking floppy disks for bad sectors

[devin davison]

I have a heap of floppy disks on hand. Most with old junk on them. Some are
going bad, and have bad spots in the middle of the disk. Is there a good
utility for either windows or dos that can format a floppy and mark the bad
parts of the floppy to not be used?

If anything, such a utility can let me find what disks are having issues
and i can pitch them before i run into the aggravation of finding there is
an issue with a disk down the line.
