I have this problem from time to time in DOS as well. I don't know what causes it, but waving a really strong magnet over the disk a few times (to erase it) it sometimes fixes the problem (Honest! I have done this in the past using big donut shaped magnets taken from old DEC hard disk packs). A bulk eraser would probably work even better. Also, try formatting the bad disk on a different computer, as some floppy drives seem to deal with this problem better than others. Once you get the disk to format successfully, you should be able to reformat it on your own machine without any problem.

I've had a few disks like this… It usually happens when I do something stupid with the disk/drive (hook up cables wrong, eject during a write, etc..). Generally, a format /u takes care of it under DOS… I haven't seen a disk with this problem under linux, so I can't say what to do with linux :)
