If you're using Western Digital or SanDisk drives, download and install the latest WD Discovery suite. Reboot (this is essential) and then connect each drive. Make sure UAS is OFF for each (gear icon next to the drive). Eject, and reconnect. Problem should be solved. It solved it for my WD SSD Passport external drives. Flying once again, no beach-balls, no crashing with scary data loss messages. You might need to reformat a Time Machine to get it to be stable in backing up (APFS format with GUID partitions, encrypted too if you want to keep it secure). Hope this helps!
