Windows 11’s August servicing wave briefly looked like a potential storage disaster: users and hobbyist labs reported NVMe SSDs vanishing during large, sustained writes after installing the 24H2 cumulative update tracked as KB5063878 (and the related preview KB5062660), but Phison — the largest...
Phison’s terse lab summary — that it “was unable to reproduce” the reports that a mid‑August Windows 11 update could “brick” SSDs after more than 4,500 cumulative test hours — changed the tone of a fast‑moving controversy, but it did not close the book on a worrying, reproducible symptom set...
Phison’s terse lab update — that its engineers “could not reproduce” the NVMe disappearances reported after a recent Windows 11 cumulative update — has shifted an alarmed headlines cycle into a cautious, technical debate about reproducibility, telemetry, and how the modern storage stack fails...
Phison’s lab campaign—more than 4,500 cumulative test hours and some 2,200 cycles—says it could not reproduce the Windows 11 KB5063878 “vanishing SSD” reports, but the episode still exposes a brittle cross‑stack interaction that administrators, gamers, and system builders should treat as a live...
Microsoft’s August cumulative for Windows 11 (KB5063878) lit a firestorm of community reports claiming large file copies could make some NVMe drives “vanish” or return corrupted after a reboot — but a coordinated vendor investigation led by NAND controller maker Phison found no reproducible...
The recent Windows 11 servicing wave that included security updates KB5063878 and the related preview KB5062660 ignited a flurry of alarm when hobbyist testers and everyday users reported NVMe SSDs disappearing — in some cases permanently — during large sustained writes, and much of the early...
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 latest test summary puts the disputed SSD failures tied to Windows 11 updates into a new, uneasy middle ground: vendors and Microsoft say they cannot reproduce a widespread “bricking” problem, while a small but alarming set of user reports continues to describe drives disappearing and...
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.
Background /...
Phison says its lab work could not reproduce the Windows 11 SSD corruption reports that circulated after the August cumulative updates — but the episode exposes how fragile modern storage stacks can be when OS updates and controller firmware collide, and why backups, staged rollouts, and vendor...
Phison has confirmed it is investigating reports that a mid‑August Windows 11 cumulative update can trigger SSD instability — drives disappearing from Windows during sustained, heavy writes — and vendors, independent testers and Microsoft are coordinating forensic work while users are warned to...

Phison's latest public posture on the Windows 11 SSD scare shifts the narrative from an alleged vendor-level "bricking" spree to a coordinated investigation, but the episode leaves important questions about testing transparency, firmware distribution, and how quickly platform vendors communicate...
Phison’s latest public update frames the SSD problem that rocked Windows 11’s August rollout as an industry-wide, workload-dependent storage regression under investigation — not a single-vendor “bricking” event — but the episode exposes sharp risks in modern storage co‑engineering and offers...
Microsoft has opened an investigation after multiple community test benches, independent outlets, and SSD vendors reported that the August 12, 2025 cumulative update for Windows 11 (commonly tracked as KB5063878, OS Build 26100.4946) can cause some solid‑state drives to disappear from the...
Microsoft’s August cumulative update for Windows 11 (KB5063878) has been linked by multiple independent testers and SSD vendors to a troubling storage regression: under sustained, large write workloads some SSDs temporarily vanish from the operating system — and in a subset of reports files...
Within days of Microsoft’s August 2025 Patch Tuesday, a cluster of independent testers and community posts began documenting a worrying pattern: after installing the Windows 11 24H2 cumulative update (tracked as KB5063878, with a related preview package KB5062660), some NVMe SSDs momentarily or...
Microsoft’s August Patch Tuesday cumulative for Windows 11 (KB5063878, OS Build 26100.4946) has been linked by independent testers and multiple outlets to a narrow but serious storage regression that can make SSDs and, in a smaller set of reports, HDDs vanish from the operating system during...
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...
Silicon Motion's early reassurance — that “so far, none of our controllers are affected” by the Windows 11 update that has been making some NVMe drives disappear under sustained writes — is an encouraging datapoint, but it is provisional and incomplete: the incident remains an active...
Windows 11’s August cumulative update (KB5063878) has been linked to a reproducible storage regression that can make certain SSDs and HDDs disappear under sustained large writes, and Silicon Motion — according to community‑sourced forum responses — reports none of its controllers have shown the...
