access permission on mounted fat32 drive

[Kai Zhang]

appended this line to fstab now, still no joy
/dev/sda5      /mnt/dos    vfat    auto,owner,rw,umask=0000 0 0

 log in as myself now and 
>cd /mnt/dos
bash: cd: /mnt/dos: Permission Denied

>ls -l
d-----------  4 root users 16384 1970-01-01 01:00 dos

Pretty weird!
