Description Karen Bruner 2005-02-08 17:53:05 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.5)
Gecko/20041107 Firefox/1.0

Description of problem:
Files and directories deleted from a fat32 filesystem on a 250GB or
300Gb USB drive (Maxtor) mounted on linux box "reappear" when
filesystem is remounted on a Windows box.  Also, filesystem usage
reported by linux box does not decrease.  However, the files are no
longer visible on the linux box, even after unmounting and remounting
the drive.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. attach and partition USB drive
2. mkfs -t vfat <device>
3. mount -t vfat -o rw <device> <mountpoint>
4. copy files to drive
5. rm -rf * <mountpoint>
6. df -k <mountpoint>
7. umount drive and put on Windows box
8. find "deleted" files!

Actual Results:  Even after rm -rf everything on drive, df still
showed prior usage.  When the drive was mounted on a Windows box,
deleted files and directories were still there.

Expected Results:  df should show minimal usage (right after
formatting, 32kb are used).  File and directories should not be
visible when the drive is moved to a Windows box.

Additional info:

fsck.vfat neither "found" the "deleted" files nor freed the usage
