Using Carbon Copy Cloner to Defrag

[mikethebook]

My Mac Mini is running very slow and its not a RAM problem. But testing iDefrag showed the hard drive needs a defrag. I back up to Carbon Copy Cloner. Would booting to CCC on my external drive, erasing the hard drive through Utilities and then copying the CCC disk image back to the hard drive resolve the problem or just repeat it?

It would resolve the current problem and write the data back in continuous blocks, thus "de-fragmentising" it.

Time Machine would also get the job done.

Yes. But it is a good idea to make second clone first on another drive since if something goes wrong you can lose everything
