An easy approach, if you have both disks attached to the machine, is to 
change the fstab so that the new disk is mounted on /home and the old 
somewhere else, then log in as root and say
umount /home, which will undo the existing mapping, and
mount /home, which will create the new mapping.

If you can't mount both disks, just swap the physical drives and log in 
as root.
Root's home directory is /root, so it won't be affected by /home being 
empty,
and you can do the restore.
