Perfect!

Now please copy & paste into Terminal and hit "return."

If you get a "Warning" pop-up, click past it and enter your password at the prompt. You won't see any indication that you've entered anything, but hit "return" anyhow.

I've got absolutely no idea how long this command will take to run. It depends on HDD size, connection speed, computer speed, and block size (which I"ve adjusted to make it run faster). I'm going to guess an hour or two, and I may be WILDLY off in either direction.

Please go to /System/Applications/Utilities/Activity Monitor and look for process "dd" to ensure that the process is running after you've presumably started it in Terminal.

"dd" runs in the background, so you can go about your normal computing activities while it's running.

Please post your results when the process has run its course.
