If you've upgraded to Tiger you may have noticed that CCC does not seem to work. Apple updated the authentication sceme of AppleScript Studio (yea!) and there's a little bit of work to be done to get that part of CCC working again. I am planning an update to CCC but I do not currently have an ETA as I have some additional features and a large QA matrix. In the meantime, keep in mind that you can use the Disk Utility application to clone one disk to another as well as to create a disk image of your hard drive.
