My Passport not found for Time Machine backup
I just realized "My Passport" has not been backing up. It is no longer on my desktop where I kept it. It is in the time machine, but get message "cannot find disk." I have checked all the connections, restarted the computer, plugged it in to different ports on the computer, it just doesn't find it. Anything else I can do before buying a new one?
