After upgrading to Monterey, I cannot access any of my external drives
After upgrading to Monterey, I cannot access any of my external drives. My iMac is late 2015, 32GB ram & was running perfectly with 7 external drivers until I upgraded. So why can I not access my drives now? They could not all have "died" at the same time.
iMac 27″, macOS 11.6
