I'm considering buying an Early '08 MacBook 2.4 GHz w/ an apparently bad hard drive ("drive not recognized"). Obviously I want to test before I buy. In order to determine if the HD is the only issue w/ this MB can I remove the hard drive from my functioning MB (1st gen. Core Duo 2.0 GHz, 160 GHz HD, OS X 10.5.7) and simply install it in the non-working MB to see if it starts up? I have a spare 160 GB HD pulled from another MB, but it's wiped clean. Advice?
