Hello, I purchased a brand new My Book Studio 3TB USB 3.0 drive (WDBHML0030HAL-NESN) for use with a Macbook Pro Retina and OS 10.9.2. In System Preference, I am able to specify the drive as a Start-up disk and it works fine.
However, when booting to Startup Manager (by pressing the Option Key at Startup), my My Book Studio does not show-up. Is this drive supposed to be bootable via USB 3.0? How I can get the drive to show-up as a bootable option?
