Great!  Gald to help.  Now what I would do is re-install the Seagte
drive, boot up and then once you've identified it properly, I would
wipe the beginning of the disk with:

  dd if=/dev/zero of=/dev/sd<letter> count=10000

where <letter> would *probably* be 'b' without quotes.  But confirm!

Then just reboot the system and you should see only the boot disk,
along with a new blank disk.  Then you can do what you want with it.
