Hi Reggie,
Is your new hard drive Serial ATA or Parallel ATA?
Have a look at this
link to Seagate, you can download the discwizard from there which will help on how you want the new drive installed.e.g. how many partitions etc.
Let me know how you get on with the discwizard and we will take it from there.
Have a look at the pictures and check your settings.
EDIT: Just a thought, check that your BIOS is set to autodetect.
Regards
