My secondary HD has 1tb capacity it was added after an install of a earlier version of Ubuntu. I've been able to set it up to mount manually no matter how I try I can't set it up to mount automatically on boot up. I've upgraded to Ubuntu 10.04 with one problem to which I found an alternative software solution. In the magazine Ubuntu User it states system/administration/disk utility now has options for mounting drives. Has anyone used this option ? If I use it on my 1tb drive will the drive mount automatically overcoming my present manual mount setup without any problems. I'm holidaying watching humpback whales and calves so won't see replies until I return home at the end of the week.

Thank you in advance from down under

If you're willing to risk working from the command-line, I would suggest opening a terminal and doing the following;

1) Run 'man fstab' and read the "manual page" that pops up.
2) Create a backup copy of /etc/fstab (cp /etc/fstab /etc/fstab.original)
3) Run the 'mount' command (just 'mount' no additional arguments) and see what options/location the drive is mounted with.
4) Add a new line to your /etc/fstab file (WARNING: Have a boot CD available, if you mess up, you could render your system unbootable)

Note that you may want to use a simple text editor to edit the /etc/fstab file. Something like OpenOffice's Writer would be a bit of overkill. If you're a 'nano' fan, that would work. However, some of the more hardcore use 'vim' or 'emacs'.

P.S: If this helps you out, be sure to hit the "Thanks" button on the bottom-right of this post.

Good Luck!

Can you please paste the fstab content and output of fdisk command?
