I'm not sure what it is you did do, but it sounds like you didn't do a zero of the drive. If you didn't do a zero, and there are bad blocks on the drive, then those are still present and will simply cause everything to go bad again very shortly.

So stop everything. This is what you need to do.

Take the bootable duplicate you have on external drive and boot from it. Then run Disk Utility. Select the internal hard drive, select Erase, click Security Options, make sure Zero or 7-pass is selected, then click OK, then click Erase. If this is a large drive, go watch a movie or take a nap, it will be a while.

When that is all done, use Super Duper to clone your bootable external (the one you are booted on), back to the internal hard drive.

Reboot from the internal hard drive.
