I have the same problem.  It turns out that fsck_msdosfs works with
fat32 file systems created by Win98 but not those created by WinXP.

I run FreeBSD 4.9.  I assumed that the problem was that the fsck_msdosfs
in 4.9 was not being kept up to date and that the problem was possibly
already fixed in release 5.x.  (I guess not.)
