I've just downloaded superduper! and I was reading the users guide where it says that if there is any data on the desired destination drive, then it may be lost when you use superduper!, and it recommended partitioning the drive to ensure data security. I have a lot of Movies on my external HDD that I didn't want taking up space on my MacBook's 60GB drive, and a LOT of family photo's that I would cry over if lost. So here's my question. How do I partition my external HDD? I went to Disk Utility but don't know how to use it. Will I have to worry about data loss on my external HDD? UPDATE: I'm running superduper right now and began to wonder something....something critical. Once I get my computer back from apple with a wiped HDD, how do I get all of my backed up files to my internal drive? Do I just drag and drop the whole thing into the HDD icon on the desktop?
