Windows 11 version 24H2 is causing unexpected headaches for users with Western Digital’s SN770 NVMe SSDs, as the update repeatedly fails despite firmware fixes. This compatibility issue has left many PC enthusiasts scrambling for solutions while raising concerns about Microsoft’s hardware validation process.

The Core Issue: Failed Updates on WD SN770 SSDs

Users report that Windows 11 24H2 installations either freeze during the update process or fail outright when attempting to install on systems with WD SN770 drives. The problem persists even after applying Western Digital’s latest firmware updates (currently version 613000WD), which were specifically released to address Windows 11 compatibility issues.

Technical analysis suggests the failure occurs during the critical boot phase transition, where the system attempts to switch from the old OS instance to the new installation. Error logs typically show:

  • 0xC1900101 (generic installation failure)
  • 0x80070002 (file not found during update)
  • NVMe driver timeouts in system event logs

Microsoft and Western Digital’s Response

Both companies have acknowledged the issue but offer conflicting guidance:

Microsoft’s Stance:
- Officially lists the SN770 as a compatible device
- Recommends standard troubleshooting (Windows Update troubleshooter, DISM scans)
- Suggests the problem may be related to third-party drivers

Western Digital’s Position:
- Confirms firmware 613000WD should resolve compatibility
- Advises checking SSD health via Western Digital Dashboard
- Recommends secure erase and clean install as last resort

Workarounds That Actually Work

Through community testing, several effective solutions have emerged:

  1. BIOS Configuration Changes
    - Disable CSM (Compatibility Support Module)
    - Enable UEFI mode exclusively
    - Set NVMe mode to AHCI if available

  2. Alternative Installation Methods
    - Create installation media using Media Creation Tool
    - Perform upgrade via mounted ISO rather than Windows Update
    - Use setup.exe /product server command to bypass some checks

  3. Driver Management
    - Uninstall WD-specific NVMe drivers temporarily
    - Let Windows use its default NVMe driver during update

Why This Matters Beyond the SN770

This incident highlights broader challenges in the Windows ecosystem:

  • Firmware Fragmentation: NVMe drives from different manufacturers require specific handling
  • Update Validation: Microsoft’s hardware compatibility testing appears incomplete
  • User Impact: Failed updates can lead to system instability or data loss

Protecting Your Data During Troubleshooting

Before attempting any fixes, users should:

  • Create a full system image backup
  • Verify SSD health using CrystalDiskInfo or WD Dashboard
  • Document current driver versions for rollback purposes

The Path Forward

While no universal fix exists yet, the most reliable solution involves:

  1. Updating SSD firmware via Western Digital Dashboard
  2. Performing a clean install rather than in-place upgrade
  3. Reinstalling WD-specific drivers post-update

Microsoft is expected to address this in future cumulative updates, but for now, users must weigh the risks of proceeding with the 24H2 update against staying on older Windows 11 versions.
