The August update KB5063878 for Windows 11 has raised concerns among users due to issues with SSD storage devices. Reports indicate that the update causes some SSDs to disappear from systems and can potentially corrupt files, particularly in situations where SSDs are 60% full after writing 50GB of data. The problem seems to affect SSDs using Phison NAND controllers but may also impact others. Microsoft has not yet acknowledged the flaw. Users are advised to hold off on the update if they are concerned about these issues.
