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

to be nitpicking, shouldn't this rather be
cp -a /home/. /mnt
just to cover the (admittedly unlikely) case there is some hidden
file or folder in /home ?
Best regards
Michael
