My USB SSD in Realteck case - RTL 9210 NVMe is not working

Hi, GeorgeCojocariu.

Welcome to Microsoft support community.

Thanks for sharing with us, we appreciate your effort of trying to solve the problem by yourself.

Just for your information(although you might already know):

The M.2 form factor, previously referred to as NGFF, is a newer type of expansion card that is internally mounted and replaces the older mSATA standard. Unlike traditional HDDs and SSDs, M.2 drives are directly connected to the motherboard through a dedicated M.2 connector slot instead of using a cable.  In your case the M.2 could be identified by the shape of the connect pin.

On the other hand, NVMe standard for a TRNASFER PROTOCAL which utilize M.2 connection usually ; and it is used create high performance SSD drive.

So the M.2 shape does not equal NVMe, below is the rough chart I found in short time just for a reference. The problem on your side might be the  connection cable does not compatible with the NVMe standard maybe. And according to : Realtek RTL9210B | OEM Drivers; this controller specifically stated it support NVMe transfer, so the port itself should be fine.

You have to check the tech spec in this case.

I hope my explanation might help you in some way. Thanks for your support of the community. Have a smooth path towards the resolve of the problem.

*Edited, add disclaimer

It is not showing any size in disk management, It says it is online but I cannot access it. I was trying to scan of errors but is not working, I was trying to change the letter and is not working, also format is not working, message is: Windows cannot access the drive. Please help

I found the issue.

On disk management is show just the adapter and not the ssd 'cause it cannot reads. I think the adapter is not matching with my SSD. Or the pins are not the same ones like in the adapter
