I'm not sure I'd blame this on the RPi3B per se. It's supposed to be able to supply a combined 1.2A draw through its 4 USB ports. I can't find much data out there about current/power consumption by various drives, though. It would seem that the only way to be confident a particular drive wouldn't require a powered hub is to test it. As always, the power supply and power cable have to be up to the task, too.
And I need to get back to the promised Version 1 of the CDPlay

It is the drive consuming more than the 1.2A limit of the raspberry.
Luckily i remembered having an usb power meter I bought years ago to check phone chargers.
It is on the initial spin of the drive starting to read when it exceeds the 1.2A limit and the raspberry stop powering for a second then the drive stops and start again in a loop. Once the drive is spinning and playing tracks the meter shows 550/650 mA of average power consumption.
