Hi all, I have a 3 year old MacBook Pro into which I would like to fit a bigger hard drive. It is a 1.83GHz / 512Mb / 80Gb / Core Duo model. I have heard that only certain manufacturers HDD's will work with Apples's drop-protection software. Is this correct? If so, which replacement HDD maufacturer's are best suited to my MBP? Thanks i advance for any replies. Effortless.
