After updating this morning, I can't see certain G-drive hard drives on my MacBook pro. Some that I formatted over a year ago are fine. The two new most recent ones won't appear. I have checked that the finder show all hard drives. Disk utility doesn't seem them either. However, when I plug them into another MacBook pro that hasn't been upgraded they appear in the finder. What should I do?
Thanks!
I can also confirm that using the apple branded usb-c to usb-c (the one used to charge the ipad or macbooks) work to access my external drives. But to clarify, to this not all cords are created equal mantra in the comments. This is true, not all cords are created equal, only the apple-branded usb-s charging cables work, not the much faster apple-branded Thunderbolt 3 cables. They do not work. They are the ones used for fast data transfer (probably like the ones that come with your external drives, non-branded) they are noticeably thicker than the charging cords. Looks like we are going to suffer slower data transfer rates until apple resolves this major issue.
When I used the usb-c to usb-c that comes with the laptop my G-Drive finally became accessible!
such a random fix! I unplugging the Wacom tablet also and magically the G drive I popped up back on!!! Thanks for this tip!

Tried Recovery Mode?:
Try mounting these in Recovery Mode. [Hold Down: command + R upon boot]. Then, go to Disk Utility, seeing if you can mount the drive(s).

"Thanks. Disk Utility returns an error message that says it can't mount the disk."

You are welcome.
A. Verify the Connection:
Enter this code in Terminal:
diskutil list
Are these seen?
B. Single Out this User:
Try creating a new administrator user. See if this then works. If so, then it is an issue pertaining to your current user. If not, then it is an issue pertaining to the macOS.
I am far from an expert on computer technology. But simply to provide additional information. When I put the computer in safe mode all of my drives showed up. When I went back to regular mode none of them showed up. Then, after removing the wacom tablet all of them showed up. Apparently safe mode shows the computer without added devices. Have you checked this yet? Good luck.
Same here. After updating to Monterey I can't see one of my 2 G-Drive usb-c 4TB. No problem if I try to plug it in an old MacBook Pro with El Capitan installed. I saved the content of the hard disk and formatted it in ExFat. In this case it works also in Monterey. If I try to format it in Mac OS Extended or Apfs it works only into my old Macbook.
I had the same problem with my LaCie external SSD drive I use for TimeMachine. It worked for years until I upgraded to Monterrey OS 12.0.1 today. I tried the suggestion of switching to an Apple branded USB C to USB C cable instead of the one that came with the drive and it instantly recognized the drive again and was functional. I was flabbergasted why this should be so, since I was on the verge of having to buy a new drive and do a whole new back-up. Thanks for suggesting this simple fix. Why Apple support would not suggest this escapes me.
Two hard drive USB-C, 4tb, G-Drive.
Only one of two is recognized from Monterey (no problems before, until the upgrade).
I've just tried to plug it with usb-c/usb-c charge cable of my MacBook and also the second one is recognized.
Thanks for this trick, waiting for an update at least I got back my hard drive

Same thing. I looked at the manufacture date on bnoth my G-DRIVEs. The newest one, from 2020, is affected; the older one, manufactured in 2019, is working and mounted. Let's keep bumping this. The charge cable solution — it tops out at USB 2.0 speeds — is not a viable solution.
That's a rather revealing data point; it's likely that due to manufacturing issues, G-DRIVE switched to a different chipset in the newer enclosure, resulting in this issue.
That makes it feel more like the ultimate resolution will not be in macOS but rather in a firmware update for the G-DRIVE.
Excellent troubleshooting.

After hours of frustration, I found your post and sure enough, my G-Drive AmorATD drive works fine with the Apple USB-C to USB-C cable. Stranger still, I have two of these drives and one of them works fine with the original cable, the other doesn't show up on the desktop and can't be mounted, yet works fine with the Apple cable. Both drives worked fine in all versions of OS 11, so there seems to be a Monterey problem with some USB-C drives...
Do you mean an Apple USB-C to USB-C charging cable? It will work, but it tops out at really slow speeds. I’d hesitate to call it fine — more like “barely functional.”
As for your other drive working flawlessly, that was also my experience. (Two G-DRIVE mobile USB-C externals.) Can you look up the date of manufacture on both? A few posts have noted that the older drives seem to work fine after Monterey, while the more recent drives won’t mount. (My 4TB drive, manufactured in 2020, has failed to mount, but the 2TB from 2019 is fine.)
If you have the original boxes, the manufacture date is on there.
Well, I couldn't get it to work with any cable attached to my computer - but I DID manage to connect it using the USB-2 hub on a Thunderbolt display - I would imagine that other older USB hubs might work as well (the modern USB-3 hub on my BenQ monitor does not work).
But you should also be able to read it by connecting it to a mac running Big Sur or before okay, so it shouldn't need to go to a lab for retrieval.
Ungraded to Monterey yesterday and lost connection to my G drive. Found this tip of unplugging My Wacom tablet (was plugged directly to my computer ) and the minute I unplugged the tablet - my G drive popped back up again!
such a random fix but it worked!
Hello, Not sure if anyone else has posted this. I recently upgraded to Monterey and just one of my external hard drives wasn't mounting. I have two external drives; a newer G drive and a LaCie. The G drive is what stopped mounting after upgraded to Monterey. My IT figured out how to get it to mount. We had to erase the hard drive and format it as ExFat, but we had to do the erasing on an older operating system, Catalina.
Oh my gosh! 4 days, 2 days on with Apple support and this is the answer! I unplugged Wacom and restarted Mac…Bluetooth worked and my external hard drives mounted. Then I could plug Wacom back in and it worked. Somehow flag viathelens post so it shows up in searches sooner!
Really unbelievable 😵💫
My SSD hard drive and the cable worked for 2 years... and after the update to macOS Monterey, I could not use Time Machine anymore, it stopped the backup after a short moment. I tried to format the disk... and than could not see it anymore, it did get mounted. I formated on a old MacBook and finally found the above suggestion to use an Apple cable, after what every thing worked as before!
With Monterey update, can't see certain hard drives
