According to https://www.storagereview.com/review/western-digital-scorpio-blue-1tb-review-wd10jpvt
the JPVT-00A1YT0 drive does use a 4096 byte physical sector size.

The question is why one system is seeing a 4096 byte logical sector size while
the other is seeing a 512 byte logical sector size. I'd check to see if the
t480 has a firmware update available to handle the larger logical sector size.

Why?

If you refer to these:

Sector size (logical/physical): 512 bytes / 4096 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
Sector size (logical/physical): 4096 bytes / 4096 bytes

That's because the USB chipset has done that transformation. Also the
disk model changes. The computer does no longer see directly the disk,
but the view the USB chipset offers.

Garbage that usb-sata thing, it has even modified the apparent size of
the partition. If you use the disk that way, result will be corruption.

4096÷512 = 8.

Maybe fresh partition the disk on the usb thing would work, but then you
can never plug it directly again. Tape a notice about this on the disk.

That's an adapter trick to get around the 2TB limit with MBR.

https://superuser.com/questions/1271871/4k-emulation-sata-usb-controllers

"Summary:

512e drives ("1st emulation") allow you to use old drivers with new disks (since 2009!).

"4Ke controllers" ("2nd emulation") allow you to use legacy MBR with huge disks (cf. Update 2 in question)."

*******

"4Ke" - logical/physical = 4096/4096 - identical to 4Kn :(

Intenso (e.g. Memory Center)
LogiLink QP0020 (thanks Thomas Weller)

"Non-4Ke" - logical/physical = 512/4096 -

AS-Media (e.g. Anker)
inateck FD2002 (thanks Thomas Weller)
"

I don't think I can adequately explain this.

*******

The first case of this I ever saw, was in an
Areca RAID user manual I happened to be reading.
It allowed a 16TB array to be used in WinXP or something.
And it's because the sectors were 4K instead of 512.
The 32-bit MBR numbers, then allowed reference to a
16TB span (32-bit number times 4Kbyte sector).

It seems since the Areca RAID card, some other designers
have tried their hand at this "trick". The CDB sent to the
controller, must be "munged" and translated, to support
the trick. The command sent by the OS, is adulterated before
it hits the disk drive controller board.

I do not know what the name of these bodged adapters is.

The article here hasn't been updated in a while, so
it's not going to be useful to a practitioner.
In some cases, even when a company declares their
stuff is ready for 4K sectors, in fact, it isn't.
It takes a patch, if you are lucky.

In many cases, that is the "maximum size we have tested with".

I have seen adverts, that one year claim the adapter worked
with a 2TB drive, and then a few years later, it advertises
that it handles 8TB drives. There are several CDB formats,
and there is room in 48-bit LBAs to handle some pretty big disks.
The plumbing is big enough for good sized disks.

It's certainly true, that there have been quirks in the past.
Like the NAS that could not handle more than a 200GB drive
(a nice round number that has nothing to do with hardware standards).
That was a software issue (as that thing used a processor
and some sort of OS).

And you would expect with UASP, that it would be using a CDB
for the LBA address purpose. The protocol does not have to be
UASP, but the stack might still use SCSI CDB anyway. Both
Windows and Linux, use SCSI for glue. Check the very last
line in this article, for inspiration, as to where a SCSI CDB
might be hiding.

I can use the adapter with extra-caution and in a limted way to move
stuff around but I'm really looking for a better way. If push comes to
shove, a usb3/thunderbolt external drive. My desktop box has an external
sata port, that's what's missing on the laptop!

I bought this:

https://www.amazon.ca/dp/B0BV5V4TVS?psc=1&ref=ppx_yo2ov_dt_b_product_details

The 'container' hype is a bit overplayed but the adapter works.
A 3.6tb spinner used regularly in the desktop shows exactly
the samne with fdisk when connected with this adapter to the
Lenovo T480 laptop.

That is a very interesting device; I was going to buy a 'simple' adapter
for pulled spinner/s because I don't have anything, but that
'complicated' one might be a better choice; it has a lot more features
than I need, but it doesn't cost much and it could be much more
'powerful' in terms of alternate uses.

I'm trying to make sure its USB3 Type A connectivity is backward
compatible, which it must be; I'm also trying to find the device at
maiwo but they don't have a search feature.

I don't think it is there; it is a K10435 (I think). Here's a manual
for it:

K10435 (first few frames of their video, admit to part number)

We're not allowed to see honorable 12V 2A wall adapter.

JMS578. Is JMicron still in business ?

At first sight I thought I'd been had again, "just another adapter like
the junk I had before" and that Carlos told me to junk and get a
'containerized' one instead. Everyone seem to be gung-ho about
containerising, I'm just burning a Suse Micro-OS install dvd too. So the
first thing I did with the super-adapter without its container was take
a spinner from my desktop and plug it into the laptop; this resulted in
chaos before but now it seems to do fdisk the proper way. I've done no
other test with it.
