So, I've been doing a lot of recording (Logic Studio 9, iMac 2.93Ghz) and have had a significant frequency of hard drive access issues (using the internal drive). The best option is clearly an external firewire drive for audio files. I already have a nice FW800 external that I use as my Time Machine backup. I'd like to use the same drive for audio (with Time Machine disabled, of course). Will it make any difference if I create a dedicated partition, rather than just a folder? Or should I just bite the bullet and buy a new drive?
