Hi there community,
I’ve just purchased a My Book 4TB to set up as the Time Machine drive for my iMac. I plugged it in and selected the drive as the Time Machine drive but the setup process failed giving me a message about failed partitioning (I don’t remember it exactly now sorry!) But now the drive isn’t even visible on my desktop (I tried to unplug and plug in again but nothing changed). In Disk Utility it is visible as an unmounted disk but clicking “Mount” does nothing. Clicking “First Aid” gives me a failure notice with the following details:
Repairing file system.
Volume is already unmounted.
Performing fsck_hfs -fy -x/dev/rdisk5s2
File system check exit code is 8.
Restoring the original state found as unmounted.
File system verify or repair failed.
I was told that this would be a simple plug in, set up and let Time Machine go type exercise, so help would be much appreciated!!
