Answer
A Samsung NVMe drive that appears as numerous small 1GB namespaces can sometimes be recovered without an RMA. Please try the following three-step recovery process first: Drain, Secure Erase, and Firmware Update.

Important: The secure erase step permanently and irreversibly destroys all data on the drive. Back up any recoverable data first, and confirm you are targeting the correct device (/dev/nvmeX) before running any commands. Substitute your actual device and namespace identifiers (for example, nvme0 and nvme0n1) in the examples below.

Step 1 - Full Power Drain
  1. Power off the system and unplug the drive.
  2. Let it sit unpowered for at least 1-2 hours to fully drain the internal capacitor.
  3. Reconnect the drive and power the system back on.

Step 2 - Secure Erase 
  1. Identify your drives and confirm the correct device/namespace: nvme list
  2. Reset the controller: nvme reset /dev/nvme0
  3. Perform a cryptographic (secure) erase on the namespace: nvme format /dev/nvme0n1 --ses=1

Note: The --ses=1 flag initiates a cryptographic/secure erase.

Step 3 - Firmware Update

  1. List the NVMe drives: nvme list
  2. Download the firmware image to the target drive: nvme fw-download /dev/nvme0n1
  3. Check the firmware slot(s): nvme fw-log /dev/nvme0n1
  4. Commit the firmware (example uses slot 2; -a 3 activates immediately): nvme fw-commit /dev/nvme0n1 -s 2 -a 3
  5. Verify the update: nvme list

Obtaining the firmware: Please contact Supermicro Technical Support to obtain the correct firmware image for your specific Samsung NVMe drive model (for example, the PM9A3 MZQL27T6HBLA-00A07). Be sure to provide your drive's serial number so we can supply the matching firmware.

After completing the process: Please let Supermicro Technical Support know whether this three-step method successfully recovered your drive. If the drive is still not functioning correctly afterward, please contact Supermicro Technical Support so we can help with further troubleshooting and, if the drive is confirmed to be faulty, guide you on the appropriate next steps.
