Installing the latest available software update is always advisable to experience new features and enhance security. Windows 11 24H2 was one such update that included many new capabilities. However, according to some users, the update, instead of improving, is breaking their PCs, especially those with a WD Black SN770 or WD Blue SN580 SSD installed.

According to WD’s official forum, users complain about errors such as “stornvme and The driver detected a controller error on \Device\RaidPort1 or 2”, driving the PCs to Microsoft’s infamous blue screen of death. Right now, the only way to prevent this is by rolling back to the previous version of Windows 11.

The WD Black SN770 is the company’s high-end flagship SSD, and this error is said to be caused by the Host Memory Buffer (HMB) feature. This feature enables SSDs to use the system’s DRAM as a cache to offer better drive performance. According to a report by TechSpot, WD allocates 64 MB of the system memory as HMB, while the latest Windows 11 24H2 update reserves up to 200 MB of HMB, potentially causing the system to crash.

This is triggering the PC to enter the Blue Screen of Death (BSOD), and one way to fix it, for now, is to roll back to the Windows 11 23H2 update. There is also a technical fix: manually limiting the HMB memory to 64 MB from the Registry Editor app will enable users to run the latest Windows 11 24H2 update even on PCs with the aforementioned SSDs.

If you are a Windows 11 PC user, wait for a few more days before updating to the latest build, where Microsoft will likely issue an update to patch this bug in the next few days.
