MY Samsung 990 Pro shows in bios, but not in Windows (Windows 11)

[dommas]

Hello everyone. 

I just finished my fist own Pc build on a Maximus Z790 Hero and i have the following Problem:
I have 3 M.2 SSDs in my PC (WD_Black SN850X 1TB; Samsung 980 Pro 1TB, Samsung 990 Pro 2TB), and in bios and device manager i see all three, but in windows i see only the 1TB ones, the 990 Pro doesnt show for some reason.

I#ve already tried a lot of stuff but i cant find it. I tried swapping the M.2 slots, wich didnt change anything. I looked in Disk Management, but it doesnt appear there as well. But i can find it in CrystalDiskInfo, where ist shows 100% Status and zero reads and writes. But it also shows no Drive Letter. 

I really dont know what else to try or if there is a realy seay solution to my problem. Its my first pc that im setting up, but everything esle worked just fine, except this one thing. I really hope someone can help me out.

Thanks in advance guys. (some pictures i took, no clue if they are helpful)BIOSWindows990 vs 980Device managerCrystalDiskInfo

If it's right out of the box, normally it should show up without much hassle, i just finished my build 10 days ago and installed the same nvme. What i personally did upon first boot after not seeing the drive in windows was to create a partition for the drive in the "Disk Managment" tab. Keep in mind you first need to download "Samsung Magician" (Samsung's drive software) and update the drivers necessary for the SSD to run. After proceeding with these 2 steps your drive should be ready to go.

Hello, first thanks for your answer. I downloaded Samsung Magician and updated one driver. Afterwards i started Disk Management and my SSD still doesnt show up. Any other ideas what could cause this? I bought the SSD form someone, but he also sold me the 980 pro wich works just fine. Could it be that he cleaned the ssd and thats why it doesnt show up? 

Sadly im not very knowledgeable, when it comes to all that software stuff sorry.

Hello again, after updating the drivers make sure you restart your computer and then you should have a bar like in the image belown in disk management, instead of blue like the rest of your drives it has a black bar, if it's there simply right click ---> New Simple Volume ----> Next ----> Next ----> Assign a letter and press Next again ----> Next ----> Finish.

Now if you don't have a black bar drive like the one shown in the image,  make sure your motherboard BIOS are updated. If that still doesn't make it pop up, try this article i found which has a variety of solutions: https://www.diskpart.com/articles/samsung-ssd-not-initialized-8523.html

Side note: The fact that you can't see it in file explorer means the drive has no partition, which is normal for a fresh drive, once you create a partition it should pop right up in File Explorer. My best guess is your 990 Pro is alive and kickin' and just needs a partition to be created (assign volume as stated above etc etc)

Thank you very much for your answer and your help with this problem of mine!

Your guide was very simple and helpful. I also just realised it was probably there in disk management, because yesterday and today when i tried to scroll down in the list with my mousewheel nothing happened. Only when i used the bar at the side to scroll down it would actually move down and show the drive where i could create the new partition. 

Stupid error on my side tbh, but thank you very much again for your help and guidance. Creating the partition as you said worked just fine and now it shows in Windows as well! Thanks so much !!
