With Monterey update, can't see certain hard drives

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.
