[Solved]Hard drive *not* spinning up using sata/power, but *is* spinning up in USB dock

I expect you are using SATA power connectors?

IIRC some of the new drives are using a new interpretation of SATA power standard, maybe associated with the orange 3.3V connection.

Try powering using a Molex to SATA power connecter, as this doesn’t have the 3.3V, or otherwise conspire to power the drive without the 3.3V connected.
