I managed to get a similar message from mdir just the other day, but at
the time I thought that it may have been a problem with the floppy disk
or the drive itself (since I recently moved my hardware into a tower case).

I managed to copy the files eventually by running fdformat and mformat on
the disk in question, even though mdir had been able to see other files

Perhaps the disk was dodgy after all, since I haven't been able to
reproduce similar behaviour.
