New M.2 SSD not showing up in Disk Management

Leigh

Built a pc with an MPG Z490 gaming edge wifi mobo. Originally with 1TB Samsung 970 Evo Plus. Filled that up so purchased and installed a second 2TB Samsung 970 Evo Plus (all parts both original build and new disc were from Micro Center). Both disks show up as disk drives in the device manager, but the new NVMe is not showing up in Disk Management. Have updated drivers, uninstalled and reinstalled. Not sure what I am doing wrong. Any help would be greatly appreciated.

Can you please post a picture of your device manager and your disk management?

Which M.2 slot and 10th or 11 Gen CPU?

Leigh

Below are the images. It is a 10th Gen i7-10700K and the new SSD is in the secondary m.2 slot (the non-shielded slot).

The new drive is M.2_2? Keep in mind with the 10th Gen CPU, M.2_1 is inoperable. 11th Gen only.

@PowerSpec_MikeW According to MSI's website, the chipset supports 2 M.2 drives

What puzzles me, is that the M.2_1 is reading the drive as Disk 1, instead of Disk 0.

@Leigh Can you run the following command for me please?

Run Powershell or Command Prompt

Type Diskpart

Type List Disk

Please take a screenshot of that in the off chance Windows Disk Management isn't reading the drive correctly

Here it is

It does with an 11th Gen CPU. M.2_1 is not functional with a 10th Gen CPU. Most of these boards used to have stickers on the M.2_1 heatsink warning users about this.

@Leigh I am unsure why your drive is not being seen to be allocated and formatted in Windows, so it may be a setting in your bios which is preventing the drive from working properly.

@Lambdaben

My mistake. It was the 500 series boards that didn't support M.2_1 with a 10th Gen CPU installed.

@Leigh

Check storage pools.
