Linux does not work on drive letters, if you know that much then you know where to start looking for the problem.
Ubuntu should create the necessarily entries by default, so I'm not gonna troubleshoot that.
Here is a detailed description on mounting partitions in Linux, if you could give us more information we could have more easily assisted you.

As you can see, a lot to work through. I have not done my Linux good deed for the day, so here is the abridged version.
In a terminal:
Code:
ls -l /dev/disk/by-uuid
total 0
lrwxrwxrwx 1 root root 10 2011-06-29 12:07 0a2ceec0-4478-4208-bf3b-d2373edce2aa -> ../../sda3
lrwxrwxrwx 1 root root 10 2011-06-29 12:07 b8bb0f4e-a197-49ab-bec7-9f0fdcbe2b2b -> ../../sda2
lrwxrwxrwx 1 root root 10 2011-06-29 12:07 c6ac2257-948b-496c-be35-2353112487dd -> ../../sda1
lrwxrwxrwx 1 root root 10 2011-06-29 12:07 c988bead-8d9b-4e81-a168-0985be8430fe -> ../../sda4
Should look something like above. Locate the disk in question.
Once you have the UUID, those long list of numbes and characters, of the partition, copy it, then you can open the following file and edit it to mount the partition as needed.
Should look like this:
Code:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
# / was on /dev/sda3 during installation
UUID=0a2ceec0-4478-4208-bf3b-d2373edce2aa / ext4 errors=remount-ro 0 1
# /boot was on /dev/sda1 during installation
UUID=c6ac2257-948b-496c-be35-2353112487dd /boot ext2 defaults 0 2
# /home was on /dev/sda4 during installation
UUID=c988bead-8d9b-4e81-a168-0985be8430fe /home ext4 defaults 0 2
# swap was on /dev/sda2 during installation
UUID=b8bb0f4e-a197-49ab-bec7-9f0fdcbe2b2b none swap sw 0 0
Right at the bottom add the following line:
Code:
UUID=[paste uuid of disk in here] /your/mountpoint filesystem type(ext4, vfat, ntfs-3g, etc) defaults 0 2
Ctrl+o to save, ctrl+x to exit, now either mount -a or reboot to see if it worked.
If there is a problem, make sure the UUID is correct and that the mount point exists.
Hope that helps.
