My Book : device busy and partition not visible

Hi all

I have a MyBook which I can’t access anymore. Time machine has failed numerous days.

"Device busy " and the partition is not visible ( however this morning it was shortly because I perform a “control disk” from disk utility )

The next step was “repair disk” and suddenly the partition didn’t appear anymore.

Googled a zillon answers already, but I’m stuck.

Hope you guys & girls have a solution or at least a clue…

thx in advance


You could try testing the drive on a different computer and/or different cable.

Some users on the community have been able to get the drive working by updating the firmware on a different OS computer.
