PC does not see SSd m2 drive, what should I do?

Question

Solid State Drives

I bought an m2 XPG Gammix S5 SSD for 256GB, a Gigabyte B450M Gaming motherboard, the ssd is shown in the BIOS, but it is not visible in the system itself, I don’t know what the problem is - the ssd format is PCIe formatter 2280. Please tell me the solution, I will be grateful

Answer 1

Win + R (aka "Run" item) -> diskmgmt.msc-> Enter Is
the SSD visible in Disk Management? If so, create partitions and format.
If not, show if R.tester sees SSD (and how exactly): https://rlab.ru/tools/rtester.html

Answer 2

P.s. The PC is connected to a regular 512GB SSD for the system, and an HDD for files, via SATAIII cables.

Answer 3

The new disk must first be initialized in Windows, and then partitioned on it.
