First, take a backup. Things tend to go wrong if they can!

Do all of this as root. Best if no user is logged in (since
this might change the contents of /home during the procedure;
safest is if you boot in single user mode)

 - if not done yet, set up a file system of your choice (I'll
  assume ext4, adjust to taste)

  mkfs.ext4 /dev/sda4

  *THIS WILL WIPE THE CONTENT OF /dev/sda4*

 - add /dev/sda4 to your /etc/fstab:

  a line like this

  /dev/sda4 /home          ext4    defaults        0      2

  (instead of /dev/sda4 you can insert the disk's UUID, which
  you find out with "sudo blkid /dev/sda4". This has the advantage
  that the blkid is sometimes more stable than the device name)

  Adjust your file system 

  *DON'T REBOOT YET*

 - copy the content of /home to your new disk:
  for example
  - mount /dev/sda4 somewhere suitable:

    mount /dev/sda4 /mnt

  - copy the contents of /home to its future location:

    rsync -av /home/ /mnt/
    (slashes are important)

    or cp -a /home/* /mnt

  - test your setup. Either issue "mount -a" and login as normal user
    or just reboot normally (if you were in single user mode, just
    reboot). All working?

  - if yes, you can wipe the content of your old /home, which is
    still taking up space on your /dev/sda3:

  - boot into single user mode

  - unmount /home (which is now /sda4)

    umount home

  - now your old home becomes visible. Wipe it

    rm -Rf /home/*

  - reboot. Done!

You didn't forget to take a backup, did you?

Don't hesitate to ask if anything is unclear. Proceed with caution!

Cheers
