I've got a 500 GB HD in my Intel iMac. I've got a a 500 GB external HD that Time Machine keeps maxed out. I want to partition the external HD to make room for my iTunes music file. I know that partitioning will erase everything. Questions: 1. When I start up Time Machine after partitioning, will it do a full back up? 2. How do I move my iTunes music file to the external HD? 3. After I move it, will it still behave the same? Any other tips about what I'm wanting to accomplish will be appreciated. Thanks. Allan
