Unable to mount an external USB-C G Drive in Monterey.

Unable to mount an external USB-C G Drive in Monterey. Unable to verify and repair fully in Disk Utility. Gives a problem with disk management when trying to mount/unmount or eject. Looks like a new software issue. Anyone else have this problem?

I've the same problem with my MBP 13" 2019 (Intel) and a G-DRIVE USB-C after I have updated to Monterey.

After some time spent with Apple support they suggested me to try with an other cable usb-c to usb-c and... surprise: with the original Apple cable (that I use to charge my MBP) the G-drive works perfectly!

I think it's caused by a bug and I hope Apple resolve it with next minor update.

I am also having this problem with an external NVME drive on an M1 Mini. When I plug it in with USB-C, it ejects improperly. Tried swapping cables, same problem. When I plug it into another Mac running Big Sur, it works fine. When I plug it in with a USB 3 cable it works fine. I tried plugging in another USB-C drive, same problem –ejects improperly. This problem started as soon as I upgraded to Monterey.

Interesting, the G-Drive is a mobile USB-C drive 3.1 Gen 1 which comes with both USB-C to USB-C and USB-C to USB-A adapters. I have two of these drives and both power up and can be seen in Disk utility using either of the adapters. However they cannot be mounted and therefore cannot be manipulated, read/write, repair or ejected. I have an old internal Hitachi disk formatted Journaled HFS+ running for a second Time Machine backup through a USB 3.0 Icy Dock that has not had an issue. Must be a new software glitch that does not like G-Drive. I'll just have to await the next Monterey software update to see if I can get them mounted again. Such is life!

I am having a somewhat similar issue. I have a few WD external spindle drives (USB-A). Plugged into a thunderbolt-3 docking station and a separate USB-A to USB-C dongle. On both occasions, it took a good 45 seconds to a minute for Montery to recognize and mount the drive. Once it mounted, it seemed ok. Took about the same amount of time to eject as well. Tried multiple drives with same result as well.

Hey leobatta, that is brilliant, great to hear that Apple gave a solution.


I saw many similar problem comments on the G-Technology community website and it appeared that WD G-Tech support did not have an answer.


Now, why didn't I think to do that? As soon as I connected the G-Technology G Drive with my Apple USB-C to USB-C cable, in fact I tried 2, the drive immediately mounts and is a quarter way through the back-up. Thanks


Now to await a software update so that I can use the drive's original cable.

Same problem. New 14” MacBook Pro. Bought WD G-drive, supposed to be plug and play. 4 hours later with multiple calls with WD, their solution was to find another computer and try and connect the drive and reformat it to exFAT. Didn’t want to do that, old format, not sure other limitations. So then the tech wanted me to type some code in the command line which I refused (his typing was poor so I was concerned i would screw something up on my laptop), then he wanted to remote in to my computer (no way), so I asked for my money back and was told I would have to pay shipping etc. really poor customer service from WD.


So then I happened on this thread and thought, what the heck, order a USB-C to USB-C cable from Apple as suggested, and … voila!!! It recognized it, set it as backup drive, works terrific. So until or if Apple/WD fixes their incompatibility. Consider spending $20 for an Apple cable. thanks Leomaster!
