As I am sure anyone with their music on a different internal drive has noticed, not all of your internal hard disks are mounted automatically at boot. However, getting an internal hard drive to automatically mount is fairly easy.
First, reboot your computer to make sure that no other drives are mounted. Then, mount the internal drive you wish to have mount automatically. You can do this by selected the drive from the “Places” menu and entering your password.
Now, open a new terminal and enter this:
df
Look for the drive mounted at /media/disk. For me, this was /dev/sdb1.

/dev/sdb1 240362656 219662284 8490572 97% /media/disk
Quit any applications that may be using that disk (Music players, file browsers, etc.) and enter this:
sudo umount /media/disk
Once the drive is unmounted (which is should be after you enter your password) enter this:
sudo mkdir /media/disk
Then, open your fstab file:
sudo gedit /etc/fstab
In the new gedit window (which will appear after you enter your password), enter this at the bottom of the file:
/device/path /media/disk fs_type rw 0 0
Make sure to replace /device/path with the device mounted in /media/disk when you ran df. fs_type should be the file system type of the drive, probably ext3. Those are TABS, not spaces, between each item.
Save the file, and restart to make sure your drive auto-mounts.
