I found the following on another forum:
so fdisk /dev/hdd
create the partition(s) you wanted.
assume you create one partition /dev/hdd1
mke2fs /dev/hdd1 this will format your harddiskl
after format, edit your /etc/fstab
/dev/hdd1 /newpart ext3 defaults 1 2
However my HDD is SATA therefore I would replace hdd with sdb. Other than that, does the above look about right?
