I recently bought a Seagate 500 GB hard drive from Newegg for my 2.0 GHz late 2007 MacBook. Last night I installed it and started from my startup discs. However, when the computer looks for a place to install, the drive does not show up. Is my computer able to recognize this drive, or do you think the drive is faulty? Or is it something simple that I am overlooking here?
