Startup clone disk will not boot the system

I used SD to clone my system startup disk on a external SATA drive. The clone disk has a GUID partition scheme.

The Startup Disk utility in System Utilities sees both startup disks (the system and clone), but when I select the clone drive and press restart, it restarts from the system disk instead of the clone. I tried restarting and holding down the Option key; the only startup disk that shows up is the system disk.

I have a new Mac Pro running 10.6.

Any ideas appreciated.
