Mount a second hard drive in Ubuntu

To find out the name of the new hard drive (assume sdb1 for this example):
sudo fdisk -l

Choose a path and name for the mount point and create it
sudo mkdir /media/mount_point_name

Change permissions
sudo chmod 777 /media/mount_point_name

To mount the hard drive only once
sudo mount /dev/sdb1 /media/mount_point_name

To automatically mount on startup, edit the fstab file. In this example the format is fat32(vfat). Change this value according to the format of the partition, e.g. ext3.
sudo gedit /etc/fstab
add /dev/sdb1 /media/backup vfat defaults 0 0

Reload the fstab file
sudo mount -a
