Windows 11’s 25H2 enablement package is currently triggering targeted upgrade blocks for systems using certain Western Digital and SanDisk NVMe SSDs — a conservative compatibility hold that echoes the same Host Memory Buffer (HMB) firmware problems first seen during the 24H2 rollout. Users who...
Windows 11’s September Patch Tuesday brings a sizeable, feature-packed cumulative update—KB5065426 (Build 26100.6584)—that mixes small but welcome taskbar and File Explorer polish with deeper on-device AI components and an unusually large offline payload that deserves careful attention from both...

In a story that moved swiftly from Reddit threads to high-traffic YouTube videos and mainstream tech headlines, recent reports blamed Microsoft's Windows 11 updates (notably KB5063878 and KB5062660) for a rash of SSD failures. The picture that has emerged after vendor investigations is more...
Microsoft and Phison are publicly at odds over whether last month’s Windows 11 cumulative update (commonly tracked as KB5063878) caused data-loss and device‑disappearance issues on some NVMe SSDs — and the debate reveals a messy intersection of community test benches, vendor lab validation...

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...
Last month’s Windows 11 patch KB5063878 triggered a flurry of alarm among power users and IT pros after a narrow set of SSDs began disappearing under heavy write conditions — a regression serious enough that some users experienced irrecoverable data loss. This feature walks through a practical...
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 investigation insists the August Windows 11 cumulative patch did not “brick” SSDs, but the story is far from a tidy conclusion: community test benches produced a repeatable failure fingerprint, controller vendor lab work failed to reproduce the fault, and Microsoft’s...
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...
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...
Silicon Motion’s brief forum reply claiming that “none of our controllers are affected” landed as a hopeful note amid a widening industry investigation into Windows 11’s August 2025 cumulative update (KB5063878) — but the evidence available to date shows a complex, cross‑stack problem that...
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...

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 and SSD vendors have opened an investigation after multiple independent testers and users reported that the August 12, 2025 Windows 11 cumulative update (KB5063878, OS Build 26100.4946) can cause some NVMe and SATA drives to stop responding, vanish from the operating system, and — in a...
Microsoft’s August cumulative for Windows 11 24H2 (KB5063878) has been linked by independent testers and enthusiast communities to a reproducible storage regression in which certain NVMe SSDs can suddenly stop responding during sustained large writes, sometimes vanishing from Device Manager and...
Microsoft’s latest cumulative for Windows 11 24H2 has been tied to a small but serious cluster of storage failures that can make NVMe SSDs disappear during heavy writes and, in a handful of cases, leave data unreadable — a scare that underscores why updating and backup discipline still matters...

Microsoft’s August cumulative for Windows 11 (KB5063878, OS Build 26100.4946) has been tied by multiple independent community tests and tech outlets to a serious storage regression: under sustained, large sequential writes some SSDs can stop responding, disappear from Windows, and — in a...
I’ve been a Windows user for decades, certified and salaried in its administration, and I still find myself reluctantly staying on the platform while privately resenting much of what it has become. The piece forwarded here — a veteran Windows writer admitting he’s “staying on Windows, but I’m...
