Hello all,

I recently bought my macbook from a friend for real cheap because my PC was having major problems. Lately I've been getting into all sorts of different music and want to play some new games that are coming out but I do not have enough space to do so, so I'm in the situation where I need a bigger hard drive. I'm thinking I want at least a 320 and think I should go with a 7500? I found this drive on Newegg.com - Computer Parts, PC Components, Laptop Computers, LED LCD TV, Digital Cameras and more!, do you think it will work? Also how easy is it to back up all my files so when I put the HD in I can put it on the new drive. Newegg.com - Western Digital Scorpio Black WD3200BEKT 320GB 7200 RPM 16MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive -Bare Drive

Any information will help out tremendously!
