Bad news for millions of PC users — do this now.

,” with an emergency update already released. Not a good look for a mandatory security update. But now a new report suggests an even nastier surprise for some users., August’s update appears to “cause several SSD failures,” with the drives becoming “non-functional after a large data write.

” It seems “storage drives reportedly malfunction while large files are being written to them at once.”that “drives disappear from the OS ; in some cases, access to the buffered tree is possible, but files cannot be read.” This seems to be a “suspected issue with the operation of the drive cache” with a “high likelihood of file corruption.”Unsurprisingly, it’s not yet clear how widespread an issue this is, and while the list of drives suspected to be vulnerable is currently limited, it’s unlikely that many users are rushing to test their own SSDs with a large file write to see if they fail.@Necoru_cat’s testing suggests “SSDs with over 60% usage after approximately 50GB of continuous writing” are affected, with “similar symptoms on HDDs as well. Our tests suggest 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.” Microsoft has not commented as yet — although I heave reached out to see if there’s any confirmation on the reports and guidance for users.
