i just got the latest Dr. Mac OS X tip. it said something about moving all the contents of the 'home' folder to another partition, to leave just OS X stuff on the one partition. that sounds like a good idea, having a system partition, and a 'other stuff' partition. i was just wondering, if i have a partition are different partitions completely seperate from one another? example: can viruses skip over partitions? and if i did want to setup a partition, that's all done through Disk Utitlty, right? can you setup a partition while you have files and stuff on your HD, or does it have to be done when you install OS X?
