I have a dual boot System with an Ubuntu-Filesystem a Windows Filesystem and another FAT Filesystem on my harddrive. My Thunderbird configuration is on that FAT partition. I tried different tools, but they are mounting the filesystem as root, so thunderbird cannot read and write on it. Sorry for my bad english and thanks for your answers.

Let us name your data partition as FAT for simplicity, and it's device name as /dev/sda11. Of course the actual partition Label and device name could be different.

You can check your device name and it's Label (If you set label, otherwise you will be given UUID of the device) with this command. Don't worry, if you see different UUID value for your system. Just open a terminal by Pressing Ctrl+Alt+T shortcut and type

sudo blkid | grep vfat

For my system, the output is like this,

/dev/sda11: LABEL="FAT" UUID="28D3-995A" TYPE="vfat" 

You can see, I've only one FAT partition whose Label is FAT and It's device name is /dev/sda11. The most important bit of information is this device name. After you have known the device name of your Fat partition, proceed as follows:

  1. Open a terminal by Pressing Ctrl+Alt+T shortcut.
  2. Type The below command

    gksu gedit /etc/fstab

    and hit Enter. This step will open /etc/fstab file in your gedit text editor. If you are using Kubuntu, replace "gedit" with kwrite. For Xubuntu and Lubuntu, use leafpad instead of gedit.

  3. At the end of this file, Add the below line

    /dev/sda11  /media/Fat   vfat   defaults,rw,users,uid=1000,gid=1000  0    0

    My user id is 1000 and group id is 1000, so I added uid=1000 and gid=1000. Check what is your user id and group id and use them as the value of uid and gid.

    To Find your user id, type id -i your-user-name and to find your group id, type id -g your-user-name.

    After adding the line, save the file by Pressing Ctrl + S keyboard shortcut. Then exit the Text editor by Pressing Alt+F4. You can also use close

    Don't simply paste the line, replace /dev/sda11 with the actual device name of your FAT partition you found by executing sudo blkid | grep vfat command early in the answer

  4. Then Again return to the terminal and type the below command

    sudo mkdir /media/Fat

    and hit Enter.

  5. Restart your PC and see if your fat partition is correctly mounted.

I am sorry but, if I follow your instructions, it does not work. During startup ubuntu says: "The mountig of a filesystem failed." And if started, only root can mount the fat filesystem. – Ubuntuuser Sep 10 '12 at 15:23
What didn't work? in which step? What is the /dev/sdXX value of your fat partition? – Anwar Shah Sep 10 '12 at 15:26
I followed your instructions but after restarting the PC the FAT-partition was not mounted and I was not able to mount it without beeing root. – Ubuntuuser Sep 10 '12 at 16:01
DId you create the folder in /media, also check whether you typed the same folder in /etc/fstab file as mount point. This command worked for me. – Anwar Shah Sep 10 '12 at 16:10
Yes I did all what you told me. – Ubuntuuser Sep 10 '12 at 16:32

Check out this link below

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – Uri Herrera Sep 9 '12 at 17:42

Heres a guide for confusing fstab via command line for auto mount on boot. (Screenshots included)

To mount an NTFS partition at boot you need to modify the /etc/fstab file.

Use Disk Utility or the sudo blkid command to find out what is the name of the partition (sda?) then add a line to the fstab file.

Create a folder in the /media or /mnt folder (/media/Data in the following example) and add the corresponding line.

This is an example line for an NTFS partition:

/dev/sda4 /media/Data ntfs auto,rw,users,exec,nls=utf8,fmask=0022,umask=000,uid=1000,gid=1000 0 0

To modify the fstab you could press Alt+F2 and type gksudo gedit /etc/fstab. Save and reboot to test it worked.
