I have a WD My Book6TB and a My Passport 4TB. The sleep timer is set for 10 minutes, and it did work originally but not does not now. I have been working on this for a long time on and off and I think that it is a Windows problem, but I don't know how to find what is aways running to keep the drives from sleeping.

Win version 22H2 - (19045-3803)

Any Ideas?
