It could be correlation without causation, but holding off update KB5063878 for now probably makes sense.
Is a Windows 11 24H2 update nuking SSDs and HDDs? That’s the startling claim reported by Neowin. Specifically, it’s the KB5063878 update that’s said to be to blame for « storage failures that cause drives to disappear, making them and their corresponding SMART (Self-Monitoring, Analysis and Reporting Technology) unreadable by the OS. »
The report, based on a post by X user Necoru_cat, claims that « Phison NAND controllers are relatively prone to issues, with DRAM-less models from the same company tending to exhibit issues at lower write volumes. »
That’s been enough to have Phison release a statement. « Phison has recently been made aware of the industry-wide effects of the ‘KB5063878’ and ‘KB5062660’ updates on Windows 11 that potentially impacted several storage devices, including some supported by Phison. We understand the disruption this may have caused and promptly engaged industry stakeholders.
