[SOLVED] dying hard drive?

I have 2 hard drives in my system. 1 for OS and the second for home. It seems that I'm having some issues with the home hard drive. It crashed overnight and when I came to the comp, I had to reboot. On reboot it failed to complete and put me in emergency mode. I looked at the logs and saw that it seemed to be due to not being able to mount /home. I rem'd out /home in fstab and was able to boot up fine. I loaded KDE Partition Manager and checked out the SMART status and it says the status is good, but has 654 bad sectors. So is there anything I can do to save the disk or is it basically just trash now? I'm able to access the data on it, it seems, so I'm not too concerned at this point about losing info, but I'd like to keep the disk if there's some way to do some sort of repair to it.

And, if the answer is it's trash, what's the best way to clone the data from this disk to a new one? I use DD for burning images to USB drives but wonder if this would be cloning data I don't want onto the new drive, like data from the bad sectors.
