Navigating Data Security Challenges in Windows 11 After SSDs Disappear

In August 2025, many Windows 11 users encountered a troubling issue after installing the update KB5063878. Reports flooded in from across the internet detailing mysterious failures with solid-state drives (SSDs) and hard disk drives (HDDs). Users discovered that their previously functioning storage units were no longer recognized by the operating system, causing alarm and panic among those who rely on their machines for everyday tasks.

The Scope of the Problem

The most significant reports stem from users with SSDs that utilize Phison NAND controllers, notably models such as the Corsair Force MP600 and SanDisk Extreme Pro. Users have observed that if they attempt to transfer files larger than 50GB, their drives might suddenly vanish, disappearing from both the Windows File Explorer and the BIOS interface. Instead of the expected NTFS or exFAT, the partition presents itself as RAW—an indication that the system cannot read the filesystem.

This situation is alarming for countless users. When Windows prompts to format the drive, many might hastily agree, risking irreversible data loss. Adding to the complexity, those using BitLocker encryption find that while their partitions appear broken, the data remains encrypted and effectively inaccessible without specialized tools.

Microsoft’s Response

In light of these reports, Microsoft has acknowledged the issue and is currently developing a fix. While some users have found that restarting their systems resolves the problem, many others still face their drives going undetected, leaving them on the brink of data disaster. The threat to personal data security has prompted many users to seek out professional data recovery software as a precautionary measure.

Strategies for Data Recovery

Faced with this dilemma, how can users access their essential data from malfunctioning SSDs? Experts from EaseUS, a leading authority in data security, suggest several effective recovery methods. Their tools, including the widely acclaimed EaseUS Data Recovery Wizard, can help users retrieve lost or inaccessible data from both standard and encrypted drives. This software is particularly useful in emergencies, as it can recover lost partitions, helping users regain critical files when their system fails to recognize the SSDs.

The intricate deep scanning feature of EaseUS can identify a variety of file types and is designed to suit both novice and experienced users, making it accessible to everyone. Additionally, EaseUS suggests that users take precautions by backing up important data before applying any system updates to mitigate the risk of unexpected data loss.

Conclusion

For users grappling with the new challenges brought on by the Windows 11 update and those whose SSDs suddenly vanish, following the advice of data recovery experts can make all the difference. While waiting for Microsoft to resolve the issue, users can take affirmative steps to secure their data and implement recovery solutions should they need them. In this age of digital reliance, ensuring that important files remain safe and accessible is crucial. For more information on data recovery solutions, visit EaseUS.
