Finally! The real reason why SSDs are disappearing in Windows 11
The article discusses the issue of disappearing SSDs in Windows 11 after the August 2025 KB5063878 update. The problem was initially blamed on the update, but Microsoft and Phison denied any connection. However, new findings from a Chinese PC hobbyist group indicate that the issue is caused by preliminary firmware versions on certain SSDs, which were triggered by the update. Phison technicians have confirmed that the SSDs that crashed due to the Windows 11 update were using unfinished firmware versions, which were never intended for end users. The official firmware, used in the SSDs shipped to consumers, has been thoroughly tested and does not have the same anomalies. The article concludes by advising users who are experiencing the issue to update the firmware of the affected SSD, but to first backup their data before initiating the firmware update.
