Question WD_Black 2 TB SN850X NVMe SSD not seen by the system.

[magnus57]

Hi,

I am in the process of upgrading my Asrock Fatal1ty X370 professional gaming MOB to a Ryzren 7 5800X3D. That part of the upgrade has been successful. However, I am having trouble with a new SSD that I want to install it is a: WD_Black 2 TB Sn850X NVME SSD. I have a 1TB evo 960 that was and is the boot drive it works fine. When I add the SN850X the system does not see it. I have tried swapping m2. Ports between the EVO and the SN850. In any case the EVO boots up fine but the system does not see the SN850X.
When I insert the SN850 into the socket there does not seem to be must resistance like it is not making good electrical contact. But this could be in my head as I try to figure out the cause of my problem.



Any thoughts would be appreciated.



Mike

The disk needs to be activate using Disk Management.

So, if you place the 1TB evo SSD on the M2-1 slot and the 2TB WD on the M2-2 slot... then boot into Windows, the 2TB WD SSD is not showing under Disk Management?

Jojesa,
I solved this problem. I went old school and did it via the cmd prompt.
But wondering about this:

Another question:
Looking at the boot SSD (disk2) the size is 931.1 GB. It lists that 500 MB is system reserve, the boot portion is 930.51 GB and 527 MB is recovery partition. When you look in file explorer it says that there is only 175 GB free. I am wondering what is eating up all the space.

Many Thanks
Magnus

Glad you were able to initialized the disk.
Is the Disk 2 the OS boot disk?
Is that the 1TB or 2TB disk?

A 1TB drive showing as 931GB in Windows is absolutely normal and expected.
There is no lost space.

It is simply a difference in units.
Base 2 vs Base 10.
Computer vs Human.

ALL drives are like this, nothing is "missing"

I could be mistaken, but I think the OP is referring to this ↖️

Install and run either WinDirStat, or WizTree.

Run as Administrator, selecting only the drive in question.
Post a screencap here.

Also, a screencap of your Disk Management window.
