I want to upgrade my current 2010 macbook pro 13" hard drive to a 1TB one. I was going to buy this hard drive: Western Digital 1 TB Scorpio Blue SATA 3 Gb/s 5200 RPM 8 MB Cache Bulk/OEM Notebook Hard Drive - WD10TPVT , but i wanted to make sure it would work first. I will be getting a free copy of the new mac OS "Lion" in july 2011 for my imac and i figured i would install it on my macbook pro's new 1TB hard drive as well when i got it. so my questions are: 1.would this hard drive (listed above) fit in a 13" macbook pro because i heard of size problems? and if not which one would? and is western digital hard drives the best around for mac? 2.would the new OS "lion" work on my macbook pro without backing up any data from my current OS (snow leopard)? 3.would i later be able to partition the new 1TB hdd? one half lion and the other ubuntu? 4.should i get a 7200 rpm hdd instead of 5200? 5.whats the maximum upgrade of ram for the 13" macbook pro? links please. 6. and is there anything else i should upgrade on the macbook pro while i'm at it or to make it compatible for the rest of the aforementioned upgrades? thanks!
