Phison Addresses SSD Failures Related to New Windows 11 Update

Key Takeaways

1. The Windows 11 update KB5063878 is causing issues with SSDs during large file transfers, especially those with Phison controllers.
2. File transfers larger than 50 GB may render affected SSDs unrecognized and inaccessible after a restart.
3. Some SSDs can recover after rebooting, but those with Phison controllers may not be recoverable.
4. Phison is aware of the issue and is reviewing the affected controllers, but has not provided specific reasons for the failures.
5. Users are advised to avoid large file transfers and postpone updates KB5063878 and KB5062660 until a firmware update is available.

The recent update for Windows 11, identified as KB5063878, seems to be causing problems with SSDs during large file transfers. According to tests conducted by users in Japan, SSDs that use Phison controllers are particularly affected by this issue. Microsoft has not yet responded to these reports, but Phison has released a statement addressing the problem.

Details of the Issue

For those who haven’t seen our previous reports, the problem arises when a file transfer larger than 50 GB is attempted on a Windows 11 device that has been updated. Based on internal tests, many of the affected SSDs become unrecognized by the system, and after a restart, the drives may become inaccessible.

Recovery and Acknowledgment

In tests done by user @Neoru_cat, it was found that some SSDs could recover after a reboot. However, SSDs using Phison controllers may not be recoverable at all. Phison has confirmed that they are aware of the SSD failure issue linked to the latest Windows 11 update.

Although Phison did not provide specific reasons for the failures, they assured that the affected controllers are currently being reviewed. The non-affected 2 TB WD_Black SN7100 is priced at $129.9 on Amazon. Phison also indicated that they will share updates once their investigation yields results.

Future Steps

It’s possible that Phison may release a firmware update following the investigation, but they are unlikely to provide direct support to customers. This support will probably come from their partners instead. Until a firmware update is available, it’s advisable to avoid large file transfers on devices that have the latest Windows 11 update. Additionally, if the KB5063878 and KB5062660 updates have not been installed yet, it may be wise to hold off on those updates.
