I've had the same problem, and have been advised that it may be related to
swapping diskettes before the red light on the diskette drive goes out.  

In DOS, a single tasking OS, wherein when it says to swap disks,
it's ready to swap.  Under Unix, a multi-tasking, write-behind system, it's
entirely possible that the system is still writing to the floppy while it's
telling you to swap disks.

Wait for the red light to go out.
