Windows Users Advised to Save These Files on Your Personal Computer, According to Microsoft
Phison Addresses Reported Storage Device Issues
Phison, a leading manufacturer of NAND controllers, is taking steps to address issues affecting certain storage devices, including those supported by the company. The issues, which potentially impacted various storage devices, were first reported by @Necoru_cat on an unspecified date.
The reported problems seem to be related to the operation of the drive cache, with users experiencing drives disappearing from the OS and becoming unreadable, as well as a high likelihood of file corruption. This was particularly noticeable when saving large files, such as games, after Microsoft's mandatory security update in August 2025.
However, Bleeping Computer has since stated that August's Windows update did not cause SSD drive failures. Microsoft has concluded its investigation and found no connection between the update and the types of hard drive failures reported on social media.
Despite this, Phison remains committed to product integrity and the success of its partners and end users. The company is reviewing the controllers that may have been affected by the reported issues and is working with partners to address them. Phison is also engaging with industry stakeholders to ensure a comprehensive resolution.
It's worth noting that no specific partners of Phison have been mentioned in the available search results regarding the verification of controlled storage units that might be affected. Tests suggest that Phison NAND controllers are relatively prone to issues, with DRAM-less models from the same company tending to exhibit issues at lower write volumes.
Microsoft continues to monitor feedback after the release of every Windows update and will investigate any future reports. Forbes reported that Google confirmed the deletion of apps on phones through the Play Store, but this issue does not appear to be directly related to the storage device problems Phison is addressing.
Phison's statement emphasizes its commitment to the success of its partners and end users. After addressing the issue, users can now save large files again on SSD drives following Microsoft's update. The company is working to resolve the issues affecting certain storage devices, including those supported by Phison, and will provide updates as more information becomes available.
