Solution:
Root Cause: Hard Hardware Safety Shutdown Triggered by NVMe Controller
When a PCIe 5.0 NVMe controller reaches its maximum critical safety limit (typically 85°C–90°C), the drive's firmware triggers an immediate hard thermal shutdown to prevent permanent silicon destruction. The drive forcibly severs its PCIe link, causing Windows to log Event ID 157 ('surprise removed').
Step-by-Step Fix:
1.Check S.M.A.R.T. Critical Warning Flags:
Open PowerShell as Administrator and run: powershell
Get-PhysicalDisk | Get-StorageReliabilityCounter | Select-Object DeviceId, Temperature, CriticalAlarm
Verify if CriticalAlarm or thermal warning flags are flagged active.2.Perform Emergency Thermal Pad Inspection:
Unmount the drive and inspect thermal pads for signs of dry-out, melting, or incomplete contact.3.Enable Software Safety Throttling in Vendor Utility:
Open your SSD manufacturer's management tool (e.g., Crucial Storage Executive, Sabrent Rocket Control Panel).Ensure early thermal management warnings are enabled so the OS scales back IO queue depth before the drive hits hard shutdown levels.
