Thanks for the info, TattooedMac
I actually just used Time Machine today before running Maintenance, so the (very little) data I had on my Mac is backed-up to my Western Digital external HD. (I usually just keep the necessities on my Mac and keep the rest on my Ex. HD, giving my Mac plenty of space) I do have SuperDuper downloaded, and after reading your post, I think it'll be wise to do a back-up with S.D. just to be sure... another thing I found shady is some of my 'paid' programs are in folders that have a .txt file with a list of serial numbers in it, (which, I know pirated torrents come in files like that with a list of serial numbers.)
Since switching to Mac, I myself have never pirated anything. (Another story for my previous Windows use)
The only thing I really use often is Photoshop. I have music editing programs like Reason, Soundtrack Pro, MainStage, Logic Pro, and Live, and I also have some movie/photo editing software... a real multimedia computer. I do play musical instruments, so I like having Reason and Live, but I never really use them (I haven't even gotten around to learning GarageBand yet

)
Note I don't have Lion purchased on the App Store, (which, I don't mind buying it, Mac OS discs are SO much cheaper than Windows OS discs) will the format/restore wipe out the pre-loaded OS too, or will it just erase all my personal data and bring me to the welcome/set-up screen?
Edit: I just opened SuperDuper. It says in normal mode, it will erase everything on my Ex HD and use it for the image back-up, while 'Smart Mode' will erase everything but my Time Machine back-ups. Is there any way I can make it to where it won't erase anything on my Ex HD and just copy the image? I have other files on my Ex HD that are separate from my Time Machine back-up, would it be safe just to move those files to my desktop for now, let SuperDuper do it's work, then move the files back to my Ex HD? Or is there another way?
