Windows Update KB5063878 Can Cause an Issue with your SSD

What you need to know about storage issues with Windows 11 update KB5063878

As Nekorusukii explains in a summary of their testing, drives go missing in Windows 11 with SMART data unreadable. You might be able to access the buffered tree, but from there, files cannot be read.

This issue seems to occur when writing large chunks of data to certain drives; it's especially prone to occur if the file size is higher than 50GB and if the drive is more than 60% full. Worse, it appears to happen on SSDs and HDDs.

Should you encounter this issue, a system reboot might recover the drive's working state, but it can recur should you put the drive under the same strain again.

Nekorusukii tested 21 SSDs with a mix of Samsung, WD, Seagate, Corsair, SK hynix, Crucial, Solidigm, ADATA, HP, XPG, and Hanye hardware. From these results, they suspect that it's a Phison NAND controller that's most likely to cause the problem.
The suggested solution is to uninstall KB5063878 and set Windows Update to not update for 5 weeks. If a patch comes out that fixes the issue, you can always re-enable Windows update to get updates soon if that happens.

P.S. It's also said that Update KB5062660 is part of the problem. https://www.bleepingcomputer.com/new...failure-issues
