i'm going to be setting up an external firewire drive tonight after my scare from last night involving a bad program and kernel panics, and i have a few questions about how i want to set it up how i want it to set up. firstly, it's going to house data from multiple computers (mac and various pc files from several other computers). secondly, i would like it to be able to boot a clean version of os x 10.4.8 as well as back up all of my data so that i don't lose it. i'll be using superduper (the free version for now) to back up my data on my mac. thirdly, i need to access the files of the external hard drive from any computer in the house, due to #1. thanks for your help, i know it's alot of requests.
