Recently, it has been reported that Microsoft's cumulative update KB5063878 for Windows 11 24H2 has led to failures in some Solid State Drives (SSDs), particularly those equipped with controller chips from Phison Electronics. Upon installing this update, users may encounter issues where the SSD becomes unrecognized by the system during large data write operations, thereby risking data loss. This problem affects a range of SSD models, and as of yet, Microsoft has not issued an official resolution. Users are strongly recommended to exercise caution when installing this update and to regularly back up their data as a preventive measure.
