as you are working on the umsdos driver for 2.1, I sent you a report of the
problems I found. In general, I'm able to mount an umsdos FS, but after
listing it, I get some noise from my HD and the syslog is repeating these
messages:

The good thing about it: No data loss.
Recently, I mounted a umsdos FS from a ZIP drive (sdc) and wrote a file to it.
More exactly: I tried to...

If you need more info, I can try to supply ...
