USB SSD will not mounted
Since I installed MacOS 12.0.1 my SDD via USB is not available. An other external HDD is still available. Both connected direct to the Mac. I can see the SDD in the harddrive-tool, but I can not start it there and receive a failure message. Reboot, plug out and in, complete new SW installation haven’t helped. Any Idea?
