Phison Responds to False Claims About Windows 11 SSD Breaking Updates and Legal Action Against Misleading Documents

Phison is currently addressing misinformation circulating online, which falsely suggests that their SSD controllers are susceptible to a critical bug introduced by recent Windows 11 updates. The company asserts that these fraudulent documents have been misleading users and partners alike.

Fake Documents Alleging Issues with Phison-Based SSDs Due to Windows 11 Update

In light of recent updates to Windows 11, specifically KB5063878 and KB5062660, a wave of reports has emerged from users experiencing malfunctions with their SSDs, particularly during the transfer of large files. Initial claims from media outlets, including NichePCGamer, suggested that these issues were isolated to SSDs using Phison’s controllers. However, further investigations reveal that storage devices from various other manufacturers are also affected.

Responding promptly, Phison has initiated an internal review to investigate potential impacts related to their hardware and issued a public statement addressing the matter.

Phison Electronics Statement on Falsified Online Document To Whom It May Concern,

Phison Electronics has recently become aware of a falsified document that is positioned as allegedly originating from our company, and that has been shared with various customers. We wish to state unequivocally that the document in question—reproduced below—is neither an official nor unofficial communication from Phison.

Specifically, the document makes false claims regarding potential storage and data issues related to the Microsoft Windows Security Updates released on August 12, 2025. We are addressing the falsified document through appropriate legal processes.

Regarding the Windows 11 updates, current online testing reports show this may impact storage devices from multiple vendors and span across both SSDs and HDDs.

We are working closely with Microsoft to help resolve this matter. Phison appreciates the continued cooperation of our partners and peers as we work together to maintain the integrity of communications within our industry.

On August 19, 2025, Phison released its only official statement to the media and customers regarding this issue. We appreciate your patience and are currently in the process of isolating any potential problems that could cause disruption or impact end users.

In a recent update, Phison expressed concerns over these unfounded accusations surrounding their SSD controllers. An unauthorized document was disseminated only days ago to several customers and partners, stating misleading claims about “significant issues”related to specific Phison products. The company clarified that this document is entirely fictitious.

The misleading information contained in these documents creates an impression of credibility, but it has no foundation in truth. Phison emphasizes they have never issued or distributed such documents. The ongoing investigation with Microsoft aims to identify and rectify the issues arising from the Windows 11 security updates, which are affecting not just SSDs, but also hard disk drives (HDDs) across various brands.
