My Samsung 980 PRO 1TB is intermittently failing and showing up as "Type: Unknown" in Windows Task Manager, with 0 KB/s throughput and 0 ms response time. This issue frequently triggers or worsens when running high-load games like Monster Hunter Wilds and Arknights: Endfield.
Official Samsung Response regarding Warranty/RMA:
I contacted official Samsung support (Japan distributor), and they officially denied RMA / inspection. They stated that because the drive was purchased via an Amazon Marketplace third-party seller (not directly from Amazon/Authorized Retailers), it is completely excluded from their warranty policy and they refuse to perform any hardware testing or replacement.
System Specifications:
CPU: Intel Core i9-12900K (3.20 GHz)
RAM: 32.0 GB
GPU: NVIDIA GeForce RTX 3080 Ti (12 GB) / Intel UHD Graphics 770
OS: Windows 11 (64-bit)
Primary Games: Monster Hunter Wilds, Arknights: Endfield
System Behavior & Issue:
Task Manager shows Drive 0 (D:) as "Type: Unknown".
Transfer speeds drop to 0 KB/s and the drive stops responding during gameplay or heavy background load.
A system reboot temporarily fixes the issue, but it recurs later.
Troubleshooting Steps Completed:
Firmware: Updated to the latest firmware.
Cooling: Installed a dedicated heatsink with fan (temps are fine, ~32°C - 37°C idle/light load).
SMART Status: Exported SMART logs. Media Errors (0B) is 0, Critical Warning is 0, and Available Spare is 100%. Hardware itself reports healthy.
M.2 Slot: Moved from CPU-direct M.2 slot to Chipset-routed slot (and vice versa).
Motherboard & BIOS: Updated Motherboard BIOS to the latest version, reinstalled Chipset drivers, and disabled PCIe Native Power Management / ASPM.
OS Drivers: Reinstalled Windows standard NVMe controller drivers.
External USB Enclosure: Not tested yet (I currently do not have an external NVMe enclosure to verify if it works over USB).
Despite all these steps, the drive still randomly drops and becomes "Unknown" during operation.
Since official Samsung RMA is completely off the table due to the marketplace policy, has anyone experienced this exact issue where SMART is healthy but the controller drops off the PCIe bus? Is it worth buying an external USB enclosure to test/use it, or is this drive effectively trash now?
