I’m running Mint, and have an external USB drive plugged in. It is not powered - it gets its power from the mini-PC.
Occasionally I get this message and I’ve no idea why. It might be after rebooting the machine but I’m not sure (sorry).
The only thing I did with the drive is rename it (to “1tbDrive”). Could that be the problem? (I did that in the Disks application).
Now this is good advice for normies like me - using the Disks app. Much better than command line stuff. I changed the settings there and hopefully that has sorted it. Thank you!
Hope it helps, would like to know if it was the solution.
Linux does have some amazing and well designed GUI applications. Of course one could do the same in the terminal. It’s up to ones preference what to use when.
