Have you edited fstab using vi editor? If you then use : x command in command mode to save and exit the file.

For more on vi editor : -- run command,

vimtutor

# indicates comments
$ indicate commands run on shell

For example,
I will open a file called file.txt
$vi file.txt
#Now you are into vi editor -
#press "i" - you can see it saying something like insert mode is on.
# then type somthing into it
#now save and quit press "Esc" key and press : and press x and Enter
#it should get back to shell
$cat file.txt
#should display the file content.

There is an easy tutor program called "vimtutor" try it I like vimtutor
Remember you need to have root access to edit fstab, always take a backup before editing important system files like fstab.

You must have root privileges to save changes in /etc/fstab.
Execute su - command to gain root privileges. You can use nano editor to edit file.

su -
nano /etc/fstab

Press Ctrl+X, Y and hit Enter key to save file.

Everything in /etc is only editable by a root account. To make changes you have to edit it as root user.
So as devils casper says, open a terminal and type su and give the root password.
Then type nano (or gedit or any other text editor of choice)/etc/fstab.
You will find that you can also open nautilus as a normal user and drag and drop the file onto a gedit window if this makes it easier for you..
