I am not sure if I need WDCSAM64.sys or not but it was failing to load. I had some difficulty with using my Passport on a USB port. The cure on my WIN11 machine was to check for updates which was up to date, but I was directed to Advanced options and look for WD drivers under optional updates. There was one so I loaded it. Problem solved.
I went through a lot of suggestions for others to try and none were helpful imho. Sorry if this is a repeat but too many threads to go though.
