I want to buy a portable hard drive to keep my iTunes library on for DJing with Tractor Pro on my MacBook. I really like the look of the LaCie Rugged but the largest capacity of these is 1TB. My iTunes library currently stands at almost 700GB. I'm sure i wont be long maxing out a 1TB drive as i mostly buy Wav files. I'm wondering if it's possible to replace the HD in the LaCie Rugged? I'd like to replace it with a 2TB 7200rpm drive if possible.
