Hi, chings,
I just installed dual boot xp+FC9:
/dev/sda1   ntfs   (xp)
/dev/sdb1  /30G  vfat  (for data & exchange, created mount point /30G when installing)

When I login as user, the xp volume sda1 automount to desktop while the vfat /30G folder has a cross on it and can't open.
What I need is sda1 NOT automount for normal user but automount for root, and sdb1 always automount.
The mod of sdb1 is drwx------  root root, can't change even login as root.

Following are the fstab and mtab, please help how to change, thanks.

Tried to edit line 9 as:
/dev/sdb1 /30G vfat rw,users,umask=0077,shortname=winnt 0 0
and mount in command line, it response that it is already mounted. But I can't access it because permission denied.

A Fedora user. Note that in Fedora 9, there is no more 'Core', and no FC anymore.

Modify the fstab:
(change the line with /30G volume)
/dev/sdb1  /30G  vfat  defaults  0 0

Have a look at http://www.tuxfiles.org/linuxhelp/fstab.html

If you mean automount in Gnome, it should have nothing related with fstab. Try searching hal and automount in Google.

Acutually the /dev/sdb1 was mounted on /30G but denied access from normal user.
sudo ls /30G can see the contents but permission is drwx------.

I do the following:

(1)  mkdir /media/30g

(2) Within fstab, I replace the line
UUID=488B-2E77   /30G   vfat ........
with:
/dev/sdb1   /media/30g   vfat   rw,suid,dev,exec,auto,user,sync  0  0

(3) Within mtab, I replace the line
/dev/sdb1  /30G  vfat  rw  0  0
with:
/dev/sdb1 /media/30g  vfat  rw  0  0

-----------

After the above editing, upon normal user login, the sdb1 successfully mounted on desktop,
but the permission changed to : drwxr-xr-x  root root, still can't write to it.

Using sudo and root login still can't change to 777, any suggestion?
Do I still need to go for HAL?

I think initially the problem was caused by the mount point /30G created during installation, switching to /media/30g partially solved the problem.

Problem solved after googling and trial.

* change permission problem: I'm so stupid that trying to chown without umount the volume.

The solution:
(1) login as root, umount /media/30g
(2) chown username /media/30g
(3) within fstab, edit the /dev/sdb1 line as:
      /dev/sdb1  /media/30g  vfat  defaults,rw,nosuid,nodev,uhelper=hal,uid=500 0 0

After reboot and login as username, /media/30g mounted with permission:
drwxr-xr-x   username  root

Bingo!
