Microsoft and Phison have now all but closed the book on the late‑August panic: after weeks of community reports, lab reproductions and headlines warning that Windows 11 24H2’s August cumulative (KB5063878) was “bricking” SSDs, thorough vendor and Microsoft testing found no reproducible link...
Phison has publicly acknowledged and replicated a key finding first raised by the PCDIY community: a wave of disappearing and allegedly “bricked” NVMe SSDs linked in timing to Windows 11’s August cumulative update (KB5063878) appears to have been driven, in at least some test cases, by...
A cluster of community test benches and vendors dug into one of this summer’s more alarming update chases: after Microsoft’s August 12, 2025 cumulative for Windows 11 24H2 (KB5063878) some users reported NVMe drives disappearing mid‑write and, in a minority of cases, returning corrupted or...
Microsoft’s audit of the August Windows 11 cumulative update has closed one chapter of an unusually noisy storage scare, but it has left behind a tangle of reproducible community tests, partial vendor confirmations, and unanswered forensic questions that IT teams and power users should still...
Microsoft says its August Windows 11 security update (KB5063878) is not behind the recent wave of reports alleging SSDs and HDDs have been rendered inaccessible or corrupted, but the episode has exposed gaps in forensic clarity and left many users mistrustful of a conclusion drawn without a...
This week’s PC Perspective podcast episode unspools a tight, messy knot of hardware headlines: a Windows 11 patch that coincided with reports of disappearing SSDs and an industry-wide investigation, a dramatic leap in QLC NAND that promises denser consumer drives, NVIDIA’s Blackwell-era push...
Microsoft’s follow-up on the August 2025 Windows 11 update controversy closes one public chapter: after an industry-wide probe, Redmond says it found no evidence that the August cumulative update (commonly tracked as KB5063878) caused the cluster of SSD disappearances and failures reported by...
Microsoft’s recent service alert closes a week of anxious speculation by saying that the August 2025 Windows 11 update is not responsible for a wave of reported SSD disappearances and failures, but the episode leaves important forensic questions and practical lessons for power users, IT teams...
Microsoft’s latest position is unambiguous: after an internal review and partner-assisted testing, the company reports it “found no connection” between the August 2025 Windows 11 security update and the series of SSD disappearances and failures circulating on social media — but the empirical...
Microsoft’s August Windows 11 cumulative update has ignited a fraught, still‑unresolved investigation after community testers and some independent labs reported that sustained heavy write operations could cause certain NVMe SSDs to disappear from Windows — and, in a minority of cases, become...

Windows 11’s August servicing wave briefly looked like a storage disaster: community testers reported NVMe drives disappearing mid-write after installing security updates KB5063878 and KB5062660, and many fingers pointed at SSDs using Phison controllers. After an industry investigation...
Phison’s lab says the recent Windows 11 cumulative update is not “breaking” SSDs — but the episode lays bare how fragile modern storage stacks can be, how quickly panic and misinformation spread, and why conservative update practices and strong backups remain non-negotiable.

A wave of community test results and vendor confirmations this week has put the latest Windows 11 cumulative update under a harsh spotlight: several SSDs can disappear from Windows during sustained, large write operations after installing the August 12, 2025 update (KB5063878), with a...
A wave of reproducible reports and a parallel burst of misinformation have combined to create one of the more consequential Patch Tuesday headaches in recent memory: Microsoft’s August 12, 2025 cumulative for Windows 11 (KB5063878) has been linked to SSDs disappearing under sustained, heavy...
