The key is the order in which you turn on the devices. If I remember correctly, you want to turn on the external _first_, wait for it to spin up, then turn on the CPU. I think the problem you're running into is that the device isn't ready by the time FreeBSD gets to it. Perhaps tweaking SCSI_DELAY may help.
