That can take while so it should have a progress bar. Dosfsck (aka fsck.vfat) is also pretty crappy. You may need to run it up to 3 times to fix corrupted VFAT completely which makes showing progress a bit more annoying. With a worst-case full VFAT having tens of GB worth of small files, it can also take up to something like 1GB of RAM (there are some patches for this, I think one of mine (reported by another person) is still unapplied in Ubuntu Bugzilla).
