WD External Hard drive not mounting after 11.3 update
After my upgrade to 11.3 or 11.4 (late May), 2 of the western digital 1TB external drives stopped showing up. They used to work fine before the update. I have another 80GB external drive (samsung) that still works in my mac. I have also used some 32GB flash drives that works fine too. So, my port, hub etc are working fine. The 2 hard drive that is not showing up also works fine in PC. So, they are fine too.
I have made sure external drive is ticked in finder preferences. nothing is showing in disk utility either. When I mount these drives, the light goes on and then nothing happens.
Any suggestions?
