Originally Published 4 months ago — by Windows Central

The Windows 11 security update KB5063878 released in August 2025 has been reported to cause serious storage issues, including making SSDs and HDDs disappear from the OS and rendering some drives unrecoverable, especially during large data transfers. Microsoft and Phison are investigating, but users are advised to avoid large file transfers and ensure data backups until a fix is issued.
