Cannot boot from external drive where superduper smart copies

aplnub:

If you could send the system log from the failed boot drive into support, I'll take a look.

To get to it, reboot from your regular drive. Then, using Finder's "Go to folder" command, navigate to:

/Volumes/the-backup-drive/private/var/log

In there, you'll find system.log. Attach that to a mail message and bop it to support.

Thanks!
