You already have the drive mounted.. now you just need to copy your
existing home to the new drive.  (it's best if as many programs are
closed as possible while doing this)

sudo cp -ax /home/. /media/disk

After that is done, you need to find out what the uuid of the new home
partition is:

sudo vol_id /dev/sdb1


that should reveal a string of alpha-numeric characters which are your
new UUID.  it's best to copy with mouse to avoid typing errors.

Next you need to edit your fstab file

gksudo gedit /etc/fstab

Delete the line that refers to /dev/sdb1

create a new line in your fstab for home:

UUID=28107d44-f66e-4358-a2a3-a77be8002ce6 /home ext3 defaults  0       1

Note: don't copy the UUID I used above, it's the UUID for your root file
system,, be sure to paste the UUID copied from vol_id instead.


It's a very good idea to use UUID on a modern system with multiple hard
drives instead of /dev/sd[whatever].  The order of drives in /dev can
change depending on how the system is booted.

Save your changes to fstab and reboot, you should be done.
