I would check if PUIS is on. If your windows turned the PUIS on your drive that might explain the problem you described.

A lot of Windows 10 users are reporting PUIS (Power Up In Standby) problems after upgrading. The solution is to disable PUIS with a tool such as hdparm or HDAT2.

See http://answers.microsoft.com/en-us/insi ... 0cad9759c9

HDAT2 needs to be launched with the /w option to spin up the drive, ie ...

HDAT2 /w

ISTR that Hitachi's Feature Tool can also disable PUIS. Booting from a Ubuntu Live CD would also automatically spin up the drive.

Please confirm me that if you use another PCB from another compatible drive and if you swap the ROM chip to that PCB the drive will not spin at all, and if you swap just the PCB without swaping the ROM chip the drive will spin. Can you check that out with a compatible PCB ?

Yep this is the exact behaviour I am seeing.

You were right, its a PUIS issue. I have been either hot plugging or using a external USB3 dock to test the drive. I shut down and plugged it in and it spins up on boot now!

I will follow that microsoft thread to disable PUIS.

Thank you ALL for your help. You saved my the trouble of sourcing another board and then realising that it would have done absolutely nothing!
