As Microsoft rolls out its Windows 11 24H2 update, owners of certain Western Digital SSDs have been greeted with constant Blue Screens of Death

Another Windows update, another round of users complaining about crashes and bugs. While hardly news, this time around the fault is very specific but also very annoying, and it concerns Western Digital SSDs, specifically its SN770 and SN580 models. It seems that these drives just aren't ready for the 24H2 update and the result is a glut of crashes and infamous Blue Screens of Death (BSODs).

All of these troubles were flagged up by SN770/SN580 owners on Western Digital's community forums (via TechSpot). It looks like the problem revolves around something called the Host Memory Buffer (HMB). All SSDs store a map of where data is located within its flash memory chips and this constantly gets updated, as information gets deleted and added.
