One interesting thing: I recently upgraded my MBP internal HD, and used Carbon Copy Cloner to do it. I first put in my new HD in an external drive, CCC'd to it, and then installed it.

One thing I noticed: when CCC copied everything, it did so in a logical order (system files first, program files, then music/movie files), and it defragged in the process (by nature of the HFS+ file system). I confirmed this by running the demo version of iDefrag which at least lets you analyze the fragmentation on your HD. My old HD was horribly fragmented (I do a ton of small to medium file add/deletes) and the same files on my new HD were not fragmented.

Now what I have to figure out is, next time I need a defrag, can I CCC to an external drive, boot from the external drive, and CCC back to the internal drive?

Anyone had luck with this?
