Samsung T5 portable ssd backup drive
This little SSD T5 has been working fine, but I may have inadvertently disconnected it by touching an onscreen button. Now the backup won't reconnect. I tried to see if it needs updating, and the screen says it's up-to-date, so it must be connected but doesn't know it. Any ideas, Apple Community?
