Home Forums Peripherals & Multimedia Peripherals external clone won't boot

The main advantages of a backup/clone made with either SuperDuper! or Carbon Copy Cloner are:

1. One can boot from the clone, and be back in business right away.

2. Since some (most?) folks do not have a robust disk maintenance/repair program like Disk Warrior or Tech Tool Pro, they need to rely on Disk Utility for trying to do repairs. While one can boot to the Recovery Partition (assuming it got created) to access Disk Utility, it is much faster to boot to the clone, and run Disk Utility from there.

3. If one has any of those more robust programs, for them to be effective on one's internal drive, they need to be booted externally. Again, having them on a clone accomplishes that.

4. Finally, one can do 1) a complete Erase, Format, and if necessary, Partition the internal drive from the clone, and then either 2) do a restore of the clone to the internal drive, or 2) install a fresh version of the OS, and 3) use Migration Assistant to "migrate"/copy all the non-Apple stuff to the internal drive.

To me, it is much, much faster (and simpler) that trying to do that from a Time Machine backup.
