WD My Passport Studio Drive won't boot
Hi
I recently purchased a portable Western Digital My Passport Studio Drive - 500 GB, 800/400 fw. I have partitioned the drive into two partitions - one for SuperDuper, the other for storing images. The drive itself is GUID partitioned, per Disk Utility, and each partition is Mac Os Extended (Journaled).
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.
