Problem with external hard drive
When I try to back up my MacBook air to WD external hard drive, message appears stating time machine couldn't complete backup to My Passport; disc may have been ejected or disconnected from the computer. I try to do another backup, but message states next backup will occur after power is connected. Power is connected, and I don't know what to do next. Can anyone help? Do I need a new external hard drive?
MacBook Air, macOS 14.4
