hi guys. I received my WD my passport studio 2tb portable external hard drive today. I have a 15" MBP mid-2010 i7 2.66ghz with 8gb memory. I have never used an external HDD before and need help to set it up. I want to use it for time machine and backing up my itunes music, films and photos. Will time machine do all that for me or do I need to find seperate space on the external HDD to save music, photos, films and documents etc... Any help would be appreciated as to how to set it up from the beginning right out of the box, I haven't even un boxed the WD HDD yet. Thanks again from an external portable HDD virgin.
