fdisk does not format drives.

You should not need to format (low level format, i.e. lay down track
and sector information on the medium) your hard drive. Ever.

What you probaably want to do is clobber the partition table so you
can start over.

* Use fdisk and delete one partition at a time untill you've deleted
  all of them.

* Use dd to write 0s to the partition table. Something like this
  should do it:

  dd if=/dev/zero of=/dev/hda bs=512 count=2 ; sync

Do this from some other linux, like a floppy distribution
(e.g. tomsrtbt) or a live CD distribution.
