My 4TB Samsung 990 Pro Keeps Needing To Be "Re-initialised"

[Plink]

When I install my Samsung 990 Pro SSD into my M.2_2 slot It's recognised by my BIOS but when I go to "Computer Management" and initialise the disk then add a volume, it disappears and goes offline shortly after making it. When putting it into the M.2_1 slot It just isn't recognised at all by the BIOS.

Regardless, the SSD seems to be fully responsive, I can even change the LED from the Samsung Magician app, all tests on the disk seem to be up fine.

Here are the things I have tried:

• Using the Samsung app to check the health of the drive (all tests say it's fine)

• Updating all drivers and updating the BIOS

• Returning the SSD and buying a new one (same issues)

• Using "diskpart"  to online the disk

• Creating a simple GPT volume (deletes after a few moments)

• Trying a different M.2 slot

and many more...

My PC specs:

• MSI MPG B550 Gaming Plus Motherboard ATX

• Gigabyte GeForce RTX 4060 EAGLE OC ICE 8GB

• Ryzen 7 5700G

• 32GB DDR4

• 750W PSU

What are the raid settings in the bios set to ? Have you used third party software to format and partition the drive? Windows sometimes does not see new drives installed, initialization seems to absent assigning a drive letter etc.

In the BIOS, my “SATA Mode” is set to “AHCI Mode”, as apposed to “RAID Mode”. Is this what you meant?

Yes.

What is it supposed to be?

Sata mode unless your pairing drives for one of the raid modes.

Sorry I think I’m misunderstanding, “Sata Mode” is the title, the two options are AHCI mode, and RAID Mode. Which one should I have enabled?

[3Fees]

Sata mode and ahci same thing.

Have you tried one of the free software programs to align, partition, and format your Samsung 980 4TB nvme ssd drive?
