Please advise.. So confused. Two questions. I want to swap out the optical SuperDrive from an early 2008 (non-unibody) 17" MacBook Pro for a caddied, second bootable HDD (second OS). I've already determined the interface to be PATA. Limiting myself to a HDD (SSD is out for reasons of cost and technological immaturity), can anyone offer recommendations on only reliable drives? Where can this theoretically caddied HDD's specs max out? Just as important is the question of where to find the right caddy? Having a hell of a time locating a caddy with a considerable amount of reviews. It kinda bites having bought into Apple JUST as they were rolling out their unibodies; most available aftermarket products serve newer toys. Worth noting also is that she's fresh off her warranty, thrusting her officially into my domain to do with what I need. This baby serves multipurposes: intensive photo manipulating, video/ audio producing, cross-platform programming/ web designing, .. her life has been tested thoroughly (and continues to defy death . With the addition of a second drive, I figure her life will extend even further. At least a few more years?
