I own an aluminum iMac w/500 gb hard drive. The HD is acting funny, and I'm not sure if it's going bad or whether it's the result of a power surge. When I boot up, I get the "kernel panic" screen ("You need to restart your computer" etc); yet, when I boot up from my SuperDuper backup, I can see the contents of this HD and write to it.

So I want to try to restore this drive before I have it replaced. The instructions in the SuperDuper User's Guide are very minimal, and I'm not sure I understand them entirely. Page 26 states:
"Restoring files from a backup:
"Recovering a single file - or a few files - is quite easy. Just attach the external drive or mount the backup image, and drag the file back to the proper location using the Finder.
"That's all there is to it!"

So, if I want to restore my main hard drive, all I have to do is:
1) Open Finder.
2) Click on my HD backup, and
3) Drag it to my "Macintosh HD" icon?
Is that really all I have to do??? Please confirm; thanks.
