New computer: LR keeps trying to write to the wrong drive

[MPDAEF]

New Win 10 computer, which I have set up same as old computer.  I have all photos on an external drive and catalog on computer hard drive. I now have LR aware of (and using) that drive.  It's drive D; LR sends me an error message that it cannot write to drive E, so sync may not work, etc.  (I have a screenshot if needed.)  The program reads the D drive; all my photos are there and editable; and everything generally seems to be working fine.  (Running the latest version, and that's now the only catalog in my Pictures library.)

I obviously did something wrong when migrating from one computer to the other.  (I have LR on both, and the old one is working fine--I just have to move D drive from one to the other as needed.) 

Is there some way I can tell LR not to be looking for a non-existent E drive?

Screen captures would be very helpful. Use the "Insert Photos" icon to include screen captures in your reply. Do not attach files.

I would like clarification on a certain point ... what specific action in LrC causes this error about drive E?

Thanks, but I won't bother posting any screenshots. The problem was solved
by correcting the sync, which was apparently set to some invisible E drive.
I appreciate your response, though.

That message most likely comes from the following issue: in the Lightroom Sync preferences, you (still) have the E drive set as location for images that are downloaded from the cloud, like images shot with your smart phone. Change that location by clicing on the 'Choose' button.

Thanks. That has worked. I don't know how you figured that out, since
whatever that E drive was was entirely invisible to me.

It's a common problem, so as soon as I hear that there is an error that mentions sync, I know enough.
