I've had something similar in NetBSD 3.1.  I mounted the fie system read-only,
extracted, what I could, and then reformatted it under NetBSD and restored.

The MS-dos disk was just a data-disk, not a system disk.  Window$ dos
not like if its
systems disk is saved and restored with tat.

Since then - no problems
