My Passport back up files location / backing up 2 PC drives

I have recently bought a new computer and went from having all of my data on one drive, to storing my photos on a separate (internal) drive. I baked up both drives using My Passport, and thought that they were successful, but then went to check the files are in My Passport by navigating to My Passport, and I cannot find where the back up files are stored at all.

Can anyone tell me how to navigate to them to check that both drives are stored on My Passport?

Is backing up 2 drives on 1 PC even possible? Thank you!

Just bumping this… please can some one tell me where the backups should be when I navigate into the Passport? They are not showing in the obvious spots. Thanks.
