I opened up my new MacBook to replace the hard drive. Unfortunately none of my TORX screwdrivers fit the screws on the MacBook's drive caddy. Must go buy new screwdriver.
I did swap out the RAM though. My ThinkPad T60 had 4 GB of DDR2 RAM installed eventhough the T60 series only supported up to 3 GB of RAM. So I swapped the 4 GB with the MacBook's included 2 GB. So now I get to use the full 4 GB of RAM on the MacBook, and the ThinkPad gets only 1 GB less than before.
The 320 GB drive in the picture was originally intended to be used with my T60 too, but I've already got a 320 GB drive and a 250 GB drive in the ThinkPad, so I was lazy to swap out the 250 for the 320, and so the 320 had been gathering dust for months...
Strangely enough, the RAM modules, the hard drive, and the hard drive caddy all had silicon grease on them. Too much heatsink paste?
