Red Hat Bugzilla – Bug 195439
Last modified: 2007-11-30 17:11:35 EST
Description of problem:
A VFAT partition which is mounted frequently gets corrupted after adding,
changing, or deleting files.
Version-Release number of selected component (if applicable):
and earlier, but not in FC4 AFAIK
Steps to Reproduce:
1. copy, change, and/or delete files on a mounted vfat partition
2. run fsck or windows chkdsk to check for corruption.
fsck or chkdsk reports fs damage
the most common result is that deleted files end up as 'lost chains' according
to XP chkdsk,
however, I have had data loss on files edited by emacs, etc.
this is on a Dell D800 notebook, Pentium M, 1GB RAM, 100GB Seagate notebook HD.
note I have no swapfile or swap partition, period.
I have tried re-creating and re-formatting the partition; it hasn't made a
I am not having any problems with lockups or crashes.
I have not seen any problems with my ext3 partition, or my NTFS partition
Note that the corruption happens even if I never boot XP.
Also note that deleting files from XP on the vfat partition works fine. Also, XP
chkdsk always fixes the problem (but data loss still occurs on the corrupted
files). I have not tried letting fsck fix the partition.
After fixing with chkdsk, both chkdsk and fsck say the partition is fine.
