Windows 11 and SN770 fail

Internal SSD Extreme M.2 NVMe
1

I recently found out that the latest update for Windows 11 has rendered my SN770 2TB WB_BLACK card totally useless.
I have tried the following… unsuccessfully update the firmware, made registry changes, and tweaked some windows 11 settings. I even rolled back my Windows update, but to no avail. I believe that my memory card is now corrupted thanks to Windows and wonder what the course of action is now?
Thoughts?

Hi @P_Smith
Since rolling back the update and other fixes didn’t work, I recommend the following steps:

  1. Test on Another System: Check if the SN770 works on a different PC to rule out compatibility issues.
  2. Disk Management Check: Open Disk Management on Windows to see if the drive is detected but unallocated. If so, you may need to format it (note: this will erase data).
  3. Data Recovery (if needed): If the card contains important data, use trusted free data recovery software to attempt recovery before formatting.
  4. Contact Support: If all else fails, reach out to WD support for warranty service or further assistance.

I’ve done everything. Can’t rebuild it. It is seen for a second on my system, and then is gone. Can’t format it. Can’t do anything to it.
I have a message into tech support about a replacement.

I have checked all the articles and done every suggested fix.
None have worked.
