No problem creating the SuperDuper clone, or backing up. However, today, I attempted to boot from it. While it is recognized in System Preferences>Startup Disk, and I can select it, the partition will not boot. As an alternative I started up holding down the option key. Only the main HD appears.
Appreciate any guidance to get this to work correctly.

Try booting from USB instead of Firewire. I can't get the Passport Studio to boot from Firewire either, which is very annoying. Works fine from USB, but I paid nearly double for a faster Firewire 800 drive.
Someone posted that it might be a "LUN" ("Logical Unit Number") problem with the drive. Someone else I know with a different firmware version can boot his Mac via firewire, so it could be that there's an upgrade or downgrade available.
