My SD backup runs fine but I haven't been able to boot from the backup.

I tried reconnecting while booting with Option Booting gets up to about 80% and stalls. This is a from a WD My Passport Ultra that has been working for a year or two.

Is it a problem with 10.12.3?

No, I have no problem booting from 10.12.3 - send me a support email (to support) and we'll work through what's going on.
