Security update KB5063878, made available by Microsoft as part of Windows 11 24H2, brought a bug This is a critical problem that can make SSDs (and even HDDs in isolated cases) inaccessible after continuous transfer of large volumes of data. When the problem occurs, the operating system stops recognizing the device and, after restarting the computer, the partitions may appear as RAW, inaccessible to the user. Reports indicate that the bug manifests itself when you try to write more than 50 GB of continuous data to drives that are already more than 60% full.
The tester, identified as Nekorusukii, evaluated 21 SSDs from various brands (including Samsung, WD, Seagate and Crucial) and found that several of them were inaccessible. The WD Blue SA510 2 TB SATA drive was the only one that suffered permanent damage and didn't work again, even after reboot. Although it was initially thought that the problem was restricted to SSDs with Phison controllers, the bug apparently affects models with other controllers as well.
Microsoft has confirmed that it is aware of the reports and said that it is investigating the case together with market partners such as Phison. As a precautionary measure until patch official, experts recommend that users avoid transferring very large files, especially on drives that are already heavily used, and that they keep their backups updated.
