WD My Cloud drives are no longer accessible and my NEAT Scanner no longer functions as there is a communication error when trying to scan. Seems like a lot of things that connect by UBS are having problems. This is utterly ridiculous. I only upgraded to El Capitan because I got the prod from Apple that it was available. I never thought it would render my computer virtually useless for what I do 90% of the time on it. I'm REALLY PISSED!
