I have a 512GB 42mm (2242) SSD in the M.2 slot. I use that as my primary for boot, etc. Have a second drive in the conventional slot.
I just bought a 1TB of the exact same drive to upgrade the M.2 - but my Thinkpad isn't recognizing it. I know the drive is good because I have a M.2 - USB adapter and it recognizes it there.
Any thoughts? Do I need some sort of driver or BIOS update that I'm unaware of, or does the hardware simply not support this? I suppose I could initialize and format the drive in the USB slot and then see if it works in the M.2 slot, but wanted to ask the community first.

Hello and welcome,
How/where is it not recognized? Not seen in BIOS?, not in the boot menu?, not seen by your Windows (or other OS?) installer?, ...

Exactly - doesn't show up in the BIOS, doesn't show up in the Boot Menu, doesn't show up in the Disk Management. The 512GB shows up fine, but when I put the 1TB in there, it's as if nothing is in there. But I know it's not the drive because it works fine in the M.2-to-USB adapter. It could be that the BIOS doesn't support larger drives in M.2

Checking parts list:
The M.2 2242 Sata 6 GB/s would be in the WWAN slot.
The traditional Sata slot would hold a Sata 6GB/s 2.5 " SSD or a Sata HDD
would be a M.2, 2280, PCIe 3x4.
System has one HDD slot or one M.2 2280 slot exclusively for storage
Some: HDD / SATA 6.0Gb/s, 2.5" wide, 7mm high, Active Protection System
Some: SSD / SATA 6.0Gb/s, 2.5" wide, 7mm high (e.g. xxxGB SSD)
Some: M.2 SSD / PCIe NVMe, PCIe 3.0 x 2, 16Gb/s
Some: 128GB M.2 SSD / SATA 6.0Gb/s, in WWAN slot as 2nd Storage, mutually exclusive with WWAN and WiGig ****this is 2242*****
If I understand, you are trying to put 1TB M.2 2242 Sata SSD in the wwan slot, to upgrade what is there(the M.2 2242 sata SSD 512 GB)?

You need to put the 1TB 2242 in your adapter and clone the 512GB over, then swap them.
The 512GB is your boot drive.
What is your machine type and model?
Your setup sounds strange.
Your boot should be a HDD spinner or a pci/e NVME per PSREF.
If you added a 2242 Sata in the wwan slot, it would be a data drive, secondary, not a boot drive.
doesn't show up in the Disk Management.
This implies your other drive is the boot drive.
Just go into disk management and format it.

I have a 20K5S24A08. In all of my Thinkpads, I've had both an SSD in the WWAN and a conventional HD in the main bay - BUT I've used the WWAN as my C: drive to boot from and with my operating system, etc. and the conventional HD as data - because obviously it's slower but has a higher capacity. But, that conventional drive also has an operating system on it (because I once had an SSD die, so I need to be able to have a backup in case of emergencies)

Understanding now. Your OEM drive(your now secondary is bootable) as is your 2242 512GB in wwan slot.
Booting your OEM drive with 1TB 2242 device shows nada and you want this to be your future boot drive.
Will research and tell you what I find about 1 TB 2242 sata restrictions in WWAN slot. Thanks for clarifying your setup.
I added a Sata SSD to my system. Cloned the Sata HDD to SSD since I have several bays, I keep the HDD boot drive unplugged with OS there. ie, got burned as you say. My data drive is in 3rd bay HDD. I have a desktop.
I clearly understand your setup now.

Thanks. Yeah, it's odd. Not only that but, as I said, the 1TB isn't recognized in the WWAN under any circumstances, but IS recognized in the USB slot with the adapter. The only thing I can think of is that a controller on the M.2 isn't somehow being recognized by the BIOS, but through the USB adapter, it is....odd.
I'm still experimenting so maybe someone has insight. Since I don't know anyone that has gotten their hands on these new 1TB drives, I guess I'm the guinea pig! :-)

Oink. I think your hunch is right, will verify.
I do disaster recovery for a living on mainframes.
As you state, burnt. Clever works.
No one wants to boot to a blinking cursor or worse.

I should add that when the 1TB M.2 SSD is in the WWAN slot and the computer is booted from the conventional drive, it also doesn't show up in the Device Manager - not even as an Unknown Device. Again, it's as if nothing is in the WWAN slot...which, again, leads me to believe the BIOS doesn't recognize it at all.
