It's been fifteen years since I've had to do a low level format.
Modern disks just don't need it.
If you want to thoroughly erase the disk and repartition it, I suggest
using shred. You can boot from KNOPPIX or another live CD, then do
# shred -z -v /dev/hdz
Replace hdz with your disk's actual name (hda, hdb, ...)
Shred writes carefully chosen bit patterns to the disk that are
designed to make it impossible to read the original contents. It
writes the whole disk 25 times, so it might run for several days. (It
might not. I recently shredded a 46 GB disk on a fast computer in
about two hours.)
Once the old data is erased, partition the disk using a partitioning
program such as fdisk, disk druid, or the Linux installer of your
choice.
