Take this with a grain of salt, as Microsoft has not officially confirmed the issue at this point. According to reports, which originated from the Japanese website Niche PC Gamer, the latest security update for Windows 11 is causing issues for some users.
Here are the details:
- The issue is reportedly caused after installation of KB5063878 or KB5062660.
- KB5063878 is the final security update for Windows 11, version 24H2 that Microsoft released on this month's Patch Day.
- KB5062660 is the preview update of the update, which Microsoft released at the end of July 2025
- The issue may affect systems with solid state drives (SSD) if a) a large number of files or b) a large single file are written to the drives.
- The drive becomes inaccessible in worst case.
One of the first users to report the issue was the X-user Necoru_cat. The user noticed that the issue occurred while updating the game Cyberpunk 2077 after the latest security update for Windows 11 version 24H2 was installed on the system.
The drive that Cyberpunk 2077 was installed on became inaccessible as a consequence. The user noted, that writing more than 50 gigabytes of files continuously to the SDD with a usage rate of at least 60 percent caused the issue. However, the solid state drive would reappear after a restart and become recognized again. Writing large amounts of data to the drive would cause the issue again according to the user. Furthermore, as Niche PC Gamer notes, some SSDs may not become available again even after reboots.
Niche PC Gamer ran tests to find out more about the issue. According to the report, the following SSD are affected by the issue:
- Corsair Force MP600
- SSD with Phison PS5012-E12 controller
- KIOXIA EXCERIA PLUS G4
- Fikwot FN955
- SSD with InnoGrit controller
- Maxio SSD
- KIOXIA M.2 SSD
- SanDisk Extreme PRO M.2 NVMe 3 D SSD
The following drives appear unaffected by the issue according to tests:
- Solidigm P44 Pro
- Samsung 980
- SanDisk SSD PLUS 240GB SDSSDA-240G
The X-user ran tests as well and created a list of affected and unaffected SSDs.
Here are the SSD that were found to be affected by the issue:
