Hey thanks for the time. 120 gigs isn't nearly enough, I don't know what I was thinking back in late 2006 but it's time I got a 320 or something at least. I'm up for the surgery... I don't know much about different brands of HDs, so I was looking for advice on the market, and any other guidelines I need to know for putting an HD in the MBP. I know I gotta check to see if it takes SATA or ATA, I can't remember at this time.. is there anything particularly not good for the MBP? Do 7200 rpm drives work fine? Any general tips would be much appreciated. Thanks guys, cheers.
