Hi all, I was reading an article on how to partition my new mac book pro. Some people have commented that having a single drive is sufficient and some say its advisable to have two. A bit confused as in what to do. The other question here is I use one drive for all my downloads and apps and the other for movies n songs. Is that how partitions work ? I know I could use it the way I want it but wanted to understand whats the best way to use it ? What happens if i partition my drive into 100 gb in one and 200 gb on the other and I run out of space on one of them, is it easy to change them ?
