Well, this is of course only anecdotal, but I do not witness corruption
with any of my USB-attached umass devices. (I no longer have a floppy
drive, and I do not have a FAT partition on my HDD either, so I cannot
test that). I am using 9.0-CURRENT, rev 198667 (but the problem did not
show also on earlier revs) 

The devices that I use on and off:

- Meizu M3 Music Card audio player
- Cowon iaudio D2 audio player (According to user forums, this one is
  particularly sensitive to fs corruption)
- various USB sticks, most notably a Kingston Data Traveller 4G (I
  believe)
- Even the occasional memory stick, or SD card in card reader

However, I must also state that I never used fsck_msdosfs in the last
few years. Neither have I formatted any FAT file systems under FreeBSD for
years. Also, I always unmount the devices before removing them.
