Need help with which group to which I should post my question

I have a question about problems with a wd mybook dvr expander used with a Motorola DVR and Charter/Spectrum cable. I can’t tell from the list of groups where this question would go.

Is this what you have, if so, maybe this will help.

I would like to post a specific question about a mybook dvr expander. Which forum do I use? This doesn’t seem to fit any of the categories under “External Drives”

How about the, Ask a Question, that is at the bottom of the link I provided? That also provides a link to ask the community or use the Knowledge Base.

If not any of the above then I suggest using the, Off-Topic Discussions.
