Please forgive my lack of education on this...but I really need to be walked through the process.
How I "back up" everything? Is it dragging every file on my computer onto an external? Or is there an actual backup process? My external firewire harddrive is also formatted to work with PC's (I don't know if that's fully accurate). I can drag files from the external onto my Mac, but it won't let me modify the contents of the harddrive at all. It all works fine in conjunction with my PC which is why I think it is formatted improperly. So given those details, how do I back everything up?
Again, thank you very much for your assistance!
