I own a pre-unibody mbp (2.2 ghz, 8600GT, 4 gigs of ram) and have a seagate 500gb 7200rpm 2.5" drive in an external enclosure. I was thinking about installing it in the mbp, but it looks like you have to take the whole thing apart in order to do it. Also, I've heard on the forums that this particular drive has issues with the sudden motion sensors interfering with one another. So.. 1. will this drive cause problems will the mbp or have those issues been addressed? 2. is the install all that difficult Thanks!
