Since the Creators update I have found that sometimes but not everytime I plug in an external drive I get the sounds of it being plugged in but it doesn't appear in File Explorer. This has happened with three different types of drive. An HDD for my backups, a camera memory card and a USB drive. When this happens the next time I restart I get blue screen telling me it will restart and a repair routine that doesn't work. I have to use System Restore to get running again. Any ideas welcome.
