Core Viewpoint - Microsoft released the KB5063878 update for Windows 11 24H2 in mid-August, aimed at fixing security issues and introducing new features. However, this update has been reported to cause severe issues with SSDs and HDDs, affecting not only Windows 11 users but also those on Windows 10 and 23H2 versions [1][2]. Summary by Sections Update Details - The KB5063878 update has an internal version number of 26100.4946 and was intended to address security vulnerabilities while adding new functionalities [1]. - Other related updates for Windows 10 include KB5063709, KB5063877, KB5063871, and KB5063889, while Windows 11 also received KB5063875 [3]. Issues Encountered - Users reported that after installing the KB5063878 update, SSDs became unrecognized by the system, leading to a "drive drop" situation, particularly when installing large games like Cyberpunk 2077 [3]. - Testing revealed that if over 50GB of data was written continuously and the SSD controller usage exceeded 60%, the drive would become unresponsive, and SMART information could not be read [4]. User Experiences - Even after a system reboot, the drives might temporarily reappear, but similar write operations would lead to repeated failures, posing a risk of file corruption [5]. - A user named @Necoru_cat conducted tests on various SSD brands and models, identifying specific SSDs that were most likely to encounter issues, including Corsair Force MP600 and KIOXIA EXCERIA PLUS G4 [6]. Fault Scenarios - Two failure scenarios were identified: - NG LV.1: Drive becomes inaccessible but can be restored after a reboot. - NG LV.2: Drive remains inaccessible even after reboot, leading to total drive failure [9]. Recommendations - Users are advised to uninstall the KB5063878 update if they plan to perform extensive data writing operations to avoid potential issues. The uninstallation process can be done through the Windows settings [9]. - It is recommended to follow the 3-2-1 backup rule for data safety, ensuring multiple copies and different storage mediums [10]. Update Background - Interestingly, the KB5063878 update was released to fix severe errors in previous versions, highlighting a recurring issue where Microsoft releases updates that inadvertently introduce new problems [10][11].
