It would appear that /dev/hda4 is the partition that used to be called /home.
I suggest you edit your /etc/fstab and add an entry like this;
/dev/hda4 /home ext3 defaults 0 0
Then move the old home out of the way, create a new mountpoint and mount it. You may also need to chown your home if the userid's have changed;
# mv /home /oldhome
# mkdir /home
# mount /home
# chown -R sandy:sandy /home/sandy/
