Cannot mount on Mac

My passport was connected to Airport extreme and I got a “Disk needs repair” message. No noise on the hard drive.

Connected the external HD to my Mac but it won’t mount. I tried mounting with `diskutil mount /dev/pathToDisk` and `diskutil mount readOnly /dev/pathToDisk` but it won’t mount. The disk is formatted in the Mac OS Extended (Journaled) format (HFS+).

I downloaded WD Drive Utilities software to check the HD and it passed WD checks.

I am not sure what to do. I cannot loose the data inside the HD (should have had a backup, I know =/) and it doesn’t mount.

Does Disk Utility even see the drive?

are you getting any kind of error in you mac or any message

Disk Utility sees the Drive, but First Aid fails with error code 8, and mounting via the CLI does not work. No error messages, only when I plug the drive on the Airport extreme, which alerts me the drives need to be fixed.

I think you’ll need to use a more advanced disk repair app like Drive Genius or your other option is to ship the drive out to a data recovery service like Drive Savers

Hopefully you didn’t use the built-in 256-bit AES Encryption with WD Security software as then you would have no means to recover unless Western Digital has a recovery option which you’ll need to talk with them. WD may also offer a recovery service if the drive is still under warranty so it maybe worth your effort to check that direction first.

Update (09/30/2018)

I’m happy you were able to recovery your files!

I’m not sure I follow your direction here…

The first question: do you have your AirPort on a Surge suppressor or better yet a UPS. The issue is if the AirPort lost power (and via the USB connection the drive as well) so the wink out of power was the cause.

The second question: If this is your backup solution then I would recommend a better drive system. I don’t like one drive solutions as they put your data a risk. I use a RAID 5 solution

If you want to try to salvage your drive I would recommend you do a complete wipe and restore your data. I would still be cautious on depending on it.

Hey Dan. I was fortunate to have formatted it right from the beginning to the HFS+ file system and did not use any encryption. I got another hard drive and I am currently imaging the WD hard drive just in case.

I download software from Ontrack and it seems that it can "fix" my hd, but I am still waiting for the imaging to be complete (it turns out it takes awhile to copy 2TB).

I will check Drive Genius but it seems similar to Ontrack's solution. Thanks for the comments! :D

@danj I ended up going with your suggestion. I bought their Data Rescue software and I was able to recover all files from the hard drive, and keep their folder structure (which was something some other softwares wouldn't do). I wonder if there was a way to "repair" the drive so that I could avoid copying the files over, then formatting the drive that had the logical error, and copying them back.
