In This thread: Over here I was accused of pirating tons of applications, told I'm screwed and told that Norton was my only savior. And on top of that, back all that up. So I have. I have about 4 DVD's of stuff. An iPod with a visible copy of the music from my computer since my iPod hasn't allowed me to use iTunes to get music onto it and 30+ GB in an external hard drive. So I used 'SuperDuper!' to clone my hard drive to the external one after I deleted the stuff I have on my iPod + DVDs. But I can't boot off the external (USB 1.0 probably right?). Booting CD's is how I was able to backup my current iMac hard drive to the external hard drive. The CD has Drive 10, DiskWarrior, Disk Util, Tech Tool, SuperDuper and Carbon Copy Cloner. Sooo This is what I want to do (sorry for long windedness I dont' want people to post 'gimme more info' ) I want to reformat my iMac hard drive because obviously I have bad blocks or such. 1) Is there a 'best way' to reformat -- 2) How should I do it with ____ tool. after its formatted 3) How can I copy the data *back* to my newly formatted Hard Drive? 4) Should I finally install my copy of 10.3 (it killed my Home Dir Files Once before DAMN YOU FILEVAULT!!) and if I should when should I do it. Thank you very very very much for any step or procedure I should take alone the way!
