UMC Advisory Notice: SSD Issues on Windows 24H2

-

 We issued a warning regarding about Phison SSD failures. On August 21, mind12, a administrator of Legion server on Discord reported that Windows 11 24H2 may cause SSD failure that led to unstable versions called KB5063878 update.

mind12 said:

Microsoft Windows 11 24H2 Update (KB5063878 ) May Cause SSD Failures

Either skip the update for now or avoid sustained writes!

(As of 20th August there is no fix!)

"Community testing has identified a reproducible pattern in which certain SSDs, when running sustained sequential writes of approximately 50 GB, become inaccessible and display unreadable SMART telemetry. 

Follow-up analysis and vendor feedback to date primarily point to solid-state drives, although conclusions about traditional spinning hard disk drives remain unconfirmed."

"Microsoft and SSD vendors are investigating and have not yet published a definitive root-cause report.

Until vendors and Microsoft publish formal guidance, users with SSDs should back up important data, 

avoid long sequential transfers on systems updated to KB5063878, 

and monitor vendor and Microsoft advisories for SSD-specific firmware, driver, or OS fixes."

How I Became a Proactive Battery Monitor (Catching Issues Early)

-
Author : Felisitas Faya P. Most users notice battery problems only after something feels wrong — shorter runtime, sudden health drops, or unstable charging. By that point, degradation has already accumulated. My goal was different from the start: catch battery issues early , before they become visible, irreversible, or expensive. The Beginning: Observing, Not Assuming (2022) In 2022, I began continuously monitoring battery health on my Lenovo Yoga Slim 7 Carbon 13ITL5. Using Lenovo Vantage Battery Details alongside HWiNFO’s tray monitoring, I tracked capacity, temperature, charging behavior, and long-term trends in real usage. The purpose wasn’t to follow battery myths or chase perfect numbers. It was to understand how batteries actually age over time — slowly, quietly, and often invisibly. Expanding the Scope: Gaming Laptops and Heat (2024) In early 2024, I expanded this monitoring to my first gaming laptop, the IdeaPad Gaming 3 15ACH6. This introduced new variables: higher power draw...
