Hi, I would be picking up my MacBook (2.0 Ghz, 160 GB 5400 rpm) today. However, I feel that the hard disk space of 160 GB is not enough, especially with Boot Camp and Windows Vista. As such, I am planning on upgrading the hard disk to 320 GB, 5400 rpm. I would therefore appreciate any advice on the following issue: Should I power on my MacBook first, test it for any issues (i.e. dead pixels), then install the hard drive and Mac OS X, OR Should I immediately put in the new hard disk and install Mac OS X.
