Bootable vs file backups, VMware and partitions

[dezinnia]

thought I'd resurrect this...

I've been doing stuff in garageband, and the files it generates are huge. A five-minute song with two tracks is about 200MB...

So, I know I've got plenty of space on the computer's hard drive, but I thought I'd like to archive the garageband files to the 500GB lacie I'm using for the SD smart backup. I don't want to keep them on my computer, but I'd like to keep them SOMEWHERE. (I can turn them into AAC files for use on iTunes if I want to listen to them.)

So, I think partitioning the external drive is the way to go... I figure I'll just split the external drive into two equal partitions...

Is there any problem or disadvantage in doing this? And just using OSX's disk utility to point to the external drive is the way to do it? Any guidance or tips?

Thanks
