It’s worked fine for about 9 months. It doesn’t show up in Finder so I tried changing cables and USB ports. When that didn’t work I tried Disk Utility which sees it as “3 TB WD My Book 1140” and shows it’s mounted but a while ago I renamed the drive “Backup Drive” on a single partition and that is grayed out below the main drive name. I’m not sure what the difference is between these to but the renamed partition appears to be a sub-heading (grayed out and unmounted) under the factory name (which looks mounted but apparently isn’t).
I’ve tried erasing the drive, removing the single partition, repairing the drive using First Aid, etc. and every time it fails. I’ve used Terminal to try to unmount the disk but it just tells me it isn’t mounted anyways although it shows up in the “diskutil list” command. I then tried using the “diskutil mount” command and it said “timed out waiting to mount”.
I’m at the end of my knowledge level and have only gotten this far thanks to various forums. I haven’t tried plugging it into another computer to see if it works but will do so on Monday. In the meantime I’m hoping someone might have a suggestion.
I use this as a backup drive using Time Machine so there isn’t any critical data that I need i just want it to start backing up again. I don’t mind erasing the disk or the partition if it will allow my Mac to see the disk again. I’m just hoping the disk isn’t faulty after only 9 months. Any help would be greatly appreciated. Thanks!
