Just bought the new MBP 13 750GB Hard Drive! I was thinking of partitioning the internal drive in two, one for OS and Apps, the other one for just for video media files. I know it's still one drive, but I like the feeling of having like two and keeping the whole thing portable. A partition for video let's me format it when I need it and keep video files in a clean place. Now, partitioning the internal drive in Lion, because of this hidden partition Apple uses for Recovery Mode, is not that easy done, and I don´t want to get into complicated and dangerous install and format strategies... What do you thing of using a large disk image (maybe as big as 500 Gb), set with Disk Utility, as a virtual video media files disk? I would need to mount it every time I start the computer, but that's not a big drawback. I am using Media Composer. Thanks!
