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): kernel-2.6.16-1.2122_FC5 and earlier, but not in FC4 AFAIK How reproducible: fairly 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. Actual results: 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. Expected results: Additional info: 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 difference. I am not having any problems with lockups or crashes. I have not seen any problems with my ext3 partition, or my NTFS partition (dual-boot winXP) 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. $ sudo fdisk -l /dev/hda Disk /dev/hda: 100.0 GB, 100030242816 bytes 255 heads, 63 sectors/track, 12161 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 1 1460 11727418+ 83 Linux /dev/hda2 * 1462 2920 11719417+ 7 HPFS/NTFS /dev/hda3 2921 12161 74228332+ f W95 Ext'd (LBA) /dev/hda4 1461 1461 8032+ 83 Linux /dev/hda5 2921 12161 74228301 b W95 FAT32 Partition table entries are not in disk order $ mount /dev/hda1 on / type ext3 (rw) none on /proc type proc (rw) none on /sys type sysfs (rw) none on /dev/pts type devpts (rw,gid=5,mode=620) none on /dev/shm type tmpfs (rw) /dev/hda5 on /mnt/fatdata type vfat (rw,umask=0000) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) Please let me know if additional information is needed.
