[SOLVED] Why is M.2 drive showing half capacity?

[Jonnybow]

I just bought a brand new 1TB NVMe SSD to use as additional storage and when I install it my computer only recognizes it as 465.76GB (the exact same size as my main SSD). I have updated my BIOS to the most recent version and tried reformatting the m.2 drive but I can't figure out how to get it to show it's full capacity.

Can you show screenshot from Disk Management?

This is what it shows me.

Specific make/model, and where you purchased it from?

 

[Nemesia]

What brand and model is this SSD?

The M.2 was probably packaged wrong at the factory.

It's a WD_Black SN850 1TB, I bought it from Best Buy today.

Can you read the part number on it?
That 465GB in Disk Management is exactly what a 500GB drive would read as.

So this is what's on my device, I don't have those part numbers anywhere that I can find them. But the model number I have on device matches with a 1TB drive.

Diagnose it with WD dashboard software.
Check reported model number with software.

It may have wrong label printed on it. Or fake product.
You may have to return it.

Try cleaning the drive with diskpart clean. It may reset capacity.
(just don't accidentally clean the wrong drive)

After checking with the WD Dashboard it's definitely not the correct product. It shows it's a SN750 and not a SN850 like it's supposed to be. Thanks everyone for your help, I'll be returning this drive tomorrow.

Did you check the correct drive?
Your old drive could be SN750.

Yeah, my other hard drive is a Samsung and named very differently.

The tag can say anything, that doesn't mean it is the correct tag though.
I would format this and return it.

Another way to check is to look at Device Manager > Populate, that should show any invisible, hidden partition formatted in some unknown format.
