>Description:
Mount a Fat32 partition as /data
Instruct smb.conf to use /data as a share
Write files from a Windows XP client to the /data share
Stop samba
umount /data
mount /data
The written files are corrupted. (A md5 check will found that the md5 of the files before mount and after mount is different)
>How-To-Repeat:
Like the description.
>Fix:
Use UFS2(possibly UFS) as the backend of share instead of Fat32
