PC does not see ssd m.2?

Question

Solid State Drives

Hello! I recently assembled a PC based on
Gigabyte b450 gaming x and the mother does not see the ssd m2 western digital 240 GB
the PC does not see either in the BIOS or in the disk management as if it does not exist
although two ssd kingston work fine
What is the problem please tell me

Answer 1

The reason is simple - the disk does not fit.
There are SATA drives and there are PCIe drives.
If you insert a SATA drive and you have a PCIe bus connection there, it won't work.
If you insert a PCIe drive and your connector is connected to a SATA controller, then of course it will not work either.
Your Gigabyte b450 gaming x board has an M.2 connector connected to the PCI-E 3.0 x4 bus .
Therefore, only PCIe drives should be connected to it.
And your ssd m2 western digital 240 gb is a SATA drive , and of course it will not work.

Answer 2

Read on the manufacturer's website:
https://www.gigabyte.com/Motherboard/B450-Gaming-X...
Ultra-Fast NVMe PCIe Gen3 x4 M.2
Read on m.2 SSD
https://www.dns-shop .ru/product/f47ce68a03f23330/2...
Logical interface - SATA 3
NVMe - no
, despite the fact that the form factor is the same - m.2 specifically, the port on your mother understands NVMe SSD, i.e. operating through the PCI-Express bus lines, you have inserted a SATA SSD. Therefore, it doesn't work. You need to either change the SSD to an NVMe version, say Samsung 970 EVO, or change the mother on which this m.2 SSD will start. There is another exotic option - to buy an adapter for a PCI-Express port like this

but this is not accurate.
There is still a chance that the keys simply do not fit stupidly, tk. the m.2 port itself can be used for several types and types of
M.2 M-key keys of size 2230, 2242, 2260, 2280 and 22110, maybe this is also your case, but this is not accurate. You need to look at the location and number of pins on the SSD and the port on the motherboard
