Determine Drive

sudo lshw -C disk

sudo fdisk /dev/sdb 
<type 'n' and 'enter' for new partition>
<type 'p' for primary partition>
<type '1' to fill the entire drive with 1 partition>
<type 'w' to write partition to disk>

Format

sudo mkfs -t ext3 /dev/sdb1

Mount

$ # < grab uuid of new disk >
$ sudo blkid
$ # < create our mount point >
$ sudo mkdir /data
$ # < edit fstab for automount >
$ sudo nano -Bw /etc/fstab
   # /etc/fstab: static file system information.
   #
   # Use 'blkid' to print the universally unique identifier for a
   # device; this may be used with UUID= as a more robust way to name devices
   # that works even if disks are added and removed. See fstab(5).
