SUCCESS!!!!!!!!!!!
Since you guys tried to help me, I thought I'd share how I solved the problem with you.
My option was to purchase Spinrite and fix the unreadable portions of the C drive. However it seems as if this drive may be failing and Spinrite puts a lot of pressure on the drives it tests (I remember using it once before), so I thought that it might kill the drive if the drive was beginning to fail and then I'd be up s**t's creek without a paddle.
So I thought of a softer option - defragmenting. When I did that the only section it couldn't read was one containing my anti-virus files. That told me that the affected data wasn't vital.
I tried to clone after that, but no go. Then it occurred to me...at the 3% mark where it sticks, it asks Retry, Ignore, or Ignore All. The Retry and All options paralyze the system. But when I hit Ignore, it continues to the next problematic sector. So why not ignore every one? So I hit the "I" key about a million times and went to dinner. When I came back the drive had cloned! I'm running the cloned drive as I type this.
Now I'm going to buy a drive exactly like the cloned one and use that as my new clone.
PROBLEM SOLVED!
Thanks for trying to help me. BTW, do I need that ISO file thing to boot from a CD? Would that be helpful in the future?
