Verbatim USB not working after Monterey

I have three old Verbatim portable hard disks, all USB 2.0, and one 3.0, which I used without any problem with my MacBook Air M1 and an adapter.

The 3.0 model is my Time Machine disk, and I used successfully it to backup my Mac just a few minutes before I upgrade it from Big Sur to Monterey.

After the upgrade it doesn't appear in Finder and even Disk Utility doesn't see it.

diskutil list from the terminal answers nothing more.

The disk is correctly mounted by my wife's Air 2020 with Big Sur and the same adapter.

And the old 2.0 disks, plus a Maxtor 3.0 work with my Monterey, using the usual adapter. What's wrong with Verbatim?

Now I have ordered a new USB-C to Micro-B 3.1 cable from Amazon, to avoid adapter, I hope it helps.

Buying an original USB-USB-C adapter from Apple should solve definitely?

Well, there you go.

I have the Apple adapter and it works perfectly. I've got other brands of things, but I prefer to pay a bit more for Apple assured compatibility.

Re: "... the same adapter"

My guess is the adapter isn't compatible with Monterey. Not an uncommon situation.

What I cannot understand is that an adapter compatible with an OS version is not compatible with the following version. I can understand a bug, but not a "feature by design".

By the way the adapter is a TP-Link UC400.

I found this review:

Product bought from LDLC on 12 May 2021

Does not work on Mac

Gift sent to friends and family who bought the macbook air M1 (which is incidentally a marvel). The latter only has a USB-C port. In short, after x tests, the connected HDD is not recognized. I regret this non-conforming purchase.

Why not contact the adapter maker? I'm sure they would welcome feedback concerning their "design features" and R&D program being insufficient.

Discussion moved to adapters, but I titled “Verbatim USB…”.

The poor adapter works with Maxtor and not with Verbatim.

The USB-c cable has arrived yesterday.

Attached to the Verbatim, but Monterey doesn't see the disk.

It works correctly attached to a MBA 2020 Intel with BigSur.

What version of Monterey is installed now ?

Reason for question, was the initial Monterey 12.0.1 was having issues with USB External Drives which seems to fixed, on the most part, in the Monday December 13, 2021 update to 12.1

Rather agree with previous posing regarding Adapter. Monterey of whatever version. including the 12/1 appears from reports to very picky when Third Party Adapter are introduced into the equation.

Again, from ASC Reports the common factor is the Chipset used in the third party adapter

Understand the annoyance between Big Sur and Monterey with same adapter working on Big Sur but not Monterey.

IMHO - Monterey has been tighten up on what Third Party anything works and does not work. This appear to include Adapters, External Drives and even Internal Drives of the computer.

Example of just how High the " Walled Garden of Apple " is becoming >>

There are reports appearing on the ASC Forums regarding failed installation of Monterey on older Qualifying Apple Computers. In most cases this is related to having a NON Apple Original internal drive ?

The EFI Boot ROM included in Monterey is verifying for Original Apple Drive and if not found , may Balk or fail to upgrade to Monterey.

Reports indicate the EFI BOOT ROM is Required to Flash the Computer and is a requirement for a Successful Monterey Installation.

Conclusions are left to trial and error, at this point.
