Windows 11 software update glitch may harm Solid State Drives; learn preventive actions
Microsoft's latest update for Windows 11, KB5063878, has reportedly been causing issues with certain Solid State Drive (SSD) storage devices. The update, issued as part of the monthly Patch Tuesday security updates last week, seems to be affecting SSDs using Phison NAND controllers, such as the Corsair Force MP600 and KIOXIA EXCERIA PLUS G4, among others with InnoGrit controllers.
The concerns center around data corruption and drives disappearing from systems, particularly when these SSDs are more than 60-80% full and under heavy write loads. Reports suggest that the fault occurs after writing large amounts of data, with Windows 11 subsequently failing to see the impacted drives.
The issues are not limited to Phison NAND controllers, as similar reports have emerged involving SSDs from other manufacturers. The concerns remain sporadic, suggesting that the fault only happens in specific situations.
This is not the first time Microsoft has faced a flaw in a cumulative batch of updates. Last year, a patch caused the dreaded Blue Screen of Death crashes for users. However, Microsoft has yet to acknowledge or confirm the flaw in the latest update.
Despite the issues, Microsoft has resolved the installation issue and advises users with a failed install to refresh and resync with the update services. The company has also issued an alert to any users on Windows 10 to upgrade to Windows 11 ahead of the end of support in mid-October.
Microsoft has addressed 119 vulnerabilities across all Microsoft software in the latest update. The Windows 11 patch for 24H2 and 23H2 systems was rolled out with security updates and usability tweaks. A new feature in the update is quick machine recovery.
The company has also admitted that users may see an additional error update related to "Microsoft Pluton Cryptographic Provider" not loading because initialization failed. For users unable or unwilling to shift to the newer OS, they can sign up for Microsoft's Extended Security Updates program.
Microsoft warned about Windows Secure Boot certificate expiration in June 2026, urging individuals and businesses to update devices ahead of time to avoid failing to boot securely. The company maintains that this issue does not cause problems with Windows now and no action is required.
Reports first emerged with a post from a Japanese user, suggesting that the issue seems to occur on SSDs that are 60% full after they write 50GB of data. Similar reports have since emerged on a social media site, Reddit, with multiple users reporting problems.
As always, it's recommended to back up important data before installing updates to minimise the risk of data loss. Users experiencing issues with the latest Windows 11 update are advised to seek assistance from Microsoft support or consult online forums for potential solutions.
