Recently I've tried the latest version of Carbon Copy but I really think it has some bugs whereby it didn't copy all that it is supposed to copy. My experience: I upgraded to a larger hard drive (at that point I was using an external FW drive) so I booted up on that first FW drive, hooked up the new FW drive, and used CC to clone everything to that new drive. Problem? For some reason MAMP refused to work, with some error that some libraries are not available. So I tried booting up from the internal drive, and cloned from the first FW drive to the 2nd FW drive again. Same thing. This is the first time I ever encountered such an issue. Does CC have trouble copying from a firewire drive to another firewire drive?
