I had to send my mac in for service, I already have a bootable clone, so I made new 2nd bootable clone and erased my HD and installed a clean OS. Meantime I was using my old bootable drive to boot into another machine.

When I got my mac back I erased the HD and cloned the clone back to the internal HD. As far as I understand it this would have the effect of defragging all the files as it copied them back to the Mac.

My question is, now that my normal working bootable clone has been used to effectively defrag the HD, would it now be a good idea, to erase the bootable clone and reclone my newly defragged HD so that they are both in the same state.

I hope this made sense.
