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. -- Regards: Szilveszter ADAM Budapest Hungary
