Sadly, the hard drive on my Late 2006 Macbook just went... thankfully I have a backup. Nonetheless, I need a new drive. My local Staples has one in stock, but I just want to make sure that it is compatible. The drive I'm looking at is the Western Digital WDBABC3200ANC. The URL from Staples is http://www.staples.com/Western-Digital-Scorpio-Blue-320GB-SATA-Notebook-Hard-Drive/product_727970. I'd really appreciate some help with this. Thanks!
