I was running fsck.msdos with -aw on my Garmin USB device to try and fix a "read-only" filesystem issue. I got the following output. Running it without options does not show the issue. With -a it does again. If you can provide the proper steps to debug this for you, I can do it, but I don't know what is useful.
