My external drive was changed to Read-Only after Catalina upgrade
My external drive was changed to Read-Only after Catalina upgrade. Why would an external (non system volume) be marked read-only and items moved to "Previously Relocated Items/Security" folder? Can I regain use of my external drive to write data?
It is a 1 GB G-Technology by Hitachi old-school magnetic spin disk connected via FireWire 800 port. It is formatted Mac OS Extended. It contains Photos and iTunes files. My guess is that the Catalina install considered this drive a security risk for some reason?
