Phison’s latest public testing and community forensics have reframed the mid‑August Windows 11 SSD scare: what began as frantic reports that the Windows 11 August cumulative updates (commonly tracked as KB5063878 and the related KB5062660) were “bricking” NVMe drives now appears to be a...
Microsoft and Phison have jointly reframed a mid‑August wave of alarming NVMe disappearances and alleged “bricking” incidents: the most credible working explanation now centers on pre‑release engineering firmware present on a small subset of drives, not an inherent, platform‑wide flaw introduced...
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’s definitive update: after an internal review and partner testing, the company says the August 2025 Windows 11 security rollup did not directly corrupt or “brick” SSDs — but the incident has exposed a fragile interaction between OS updates, SSD controller firmware, and real-world...
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 blunt conclusion — that the August Windows 11 cumulative update commonly tracked as KB5063878 is not the cause of reported SSD failures — closes one chapter in a fast-moving controversy but leaves crucial forensic questions unanswered for administrators and power users who handle...

Microsoft’s investigation into reports that the August 2025 Windows 11 24H2 cumulative update (KB5063878) was bricking SSDs concludes, for now, that there is no detectable connection between the patch and the drive failures users reported — but the episode exposes how fragile trust is between OS...
Less than two weeks after Microsoft pushed the August 12, 2025 cumulative update for Windows 11 (commonly tracked as KB5063878 for 24H2), a narrow but alarming failure profile began to circulate among hobbyist test benches and end users: during sustained large file transfers (commonly around 50...
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...
Phison’s latest public stance changes the tone of what started as a panic: after industry-wide reports that a mid‑August Windows 11 cumulative update could cause NVMe SSDs to disappear during long writes, Phison says its internal testing — described as extensive — was unable to reproduce the...
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...
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 cumulative (KB5063878) for Windows 11 24H2 has been linked by multiple independent testers and industry observers to a storage regression that can make some NVMe SSDs disappear during heavy writes — sometimes temporarily, sometimes with irrecoverable damage — and the safest...
Microsoft has acknowledged an active investigation after multiple community researchers, test benches and SSD vendors reported that the Windows 11 August cumulative (commonly tracked as KB5063878, OS Build 26100.4946) can cause certain SSDs to vanish from the operating system during sustained...
Phison has warned customers that a circulated document purporting to come from the company — and claiming the recent Windows 11 security updates were uniquely breaking Phison-based SSDs — is a falsified communication, and the controller vendor says it is pursuing appropriate legal action while...
Microsoft’s August cumulative for Windows 11 (KB5063878, OS Build 26100.4946) has been linked by multiple community tests and specialist outlets to a narrow but severe storage regression in which some NVMe SSDs can suddenly become unresponsive or disappear during sustained, large writes — a...
Microsoft’s latest Windows 11 cumulative update has been linked by multiple community tests and vendor advisories to a storage regression that, under specific conditions, can make some NVMe SSDs disappear during large sustained writes — risking data corruption or loss — and has reignited a...
Phison has confirmed it is investigating reports that Microsoft’s August cumulative for Windows 11 (24H2) — distributed as KB5063878 — is associated with a storage regression that can make certain NVMe SSDs stop responding or disappear from Windows during large, sustained write operations...
