Phison Issues Statment on False Documents That Are Being Sent To Their Customers Claiming That Windows 11 SSD Breaking Updates Is Specific To Their Controllers, Taking Legal Action

Phison says that fake documents are doing the rounds online, which makes it seem like their controllers are prone to Windows 11's SSD-breaking bug.

Faked Online Documents Being Used To Make False Claims That Phison-Based SSDs Are Prone To Issues Related To Windows 11 Update

Recently, there have been several reports of the latest Windows 11 Security Updates, titled KB5063878 & KB5062660. Ever since the update, users have been reporting SSD malfunctions when writing large files were written. A few outlets, such as NichePCGamer, pushed out a list of SSDs that were affected by this. Initially, all of the drives seemed to be based around the Phison controller, but that was not the case at all. Other storage devices based on controllers from different manufacturers are also now confirmed to be affected.

Phison itself started investigating the issue around its controller to resolve the problem, and has issued a statement which you can read over here.

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. For further information about the alleged widespread issues, we encourage you to consult coverage from WCCFTech and Tom’s Hardware.

But there's something big happening behind the table. In a new statement issued by Phison, it looks like the company is being falsely accused regarding potential storage and data issues specific to the Phison controller. The document was originally shared just a few days ago with several Phison customers and partners, but the company was unaware of this and has now issued a statement that the document is entirely false.

The document is made in a way that it seems like it was from Phison itself, but that's not true. Neither is the information within the document, which talks about "Significant issues" with certain Phison SSD controllers. These false documents can be seen below:

Phison states that they never released or sent out such documents to its partners and that they are working closely with Microsoft to resolve the bug introduced with the Windows 11 security updates. Furthermore, the issue not only affects SSDs but also HDDs, and from multiple vendors, not just Phison.

It is likely that some competitor of Phison might be trying to leverage the situation and trying to create panic around Phison-based SSDs. It's a good thing that Phison figured out early as to what was going on and not only responded to the main issue but also to these false claims. We will keep you posted as this is still a developing story, and an investigation is underway on the Windows 11 update bug.
