WD releases SDD firmware fix after Windows 11 24H2 BSODs

Microsoft is investigating reports of issues with specific Western Digital SSDs affecting users of Windows 11 24H2. Users have experienced severe disruptions, including Blue Screen of Death (BSOD) errors, after installing the update. Microsoft confirmed awareness of the complaints but has not officially listed this issue among the known problems with Windows 11 24H2. Western Digital has acknowledged the problem and released a patch to address an issue with the Host Memory Buffer (HMB) for certain SSD models, which include WDBLACK SN770, WDBLACK SN770M, WD Blue SN580, WD Blue SN5000, and SanDisk Extreme M.2, all of which are 2TB models. Western Digital cautioned that Microsoft may block systems with affected models from upgrading to Windows 11 24H2 until the firmware is updated. Additionally, Windows 11 24H2 has been linked to other known issues, including problems with fingerprint sensors and Intel Smart Sound Technology drivers, as well as a reporting error in the Disk Cleanup tool.

Another day, another huge Windows 11 24H2 update bug, this time triggering the dreaded Blue Screen of Death

Users are experiencing system crashes and Blue Screens of Death (BSOD) linked to the Windows 11 24H2 update, particularly affecting Western Digital SSD models SN770 and SN580. Reports of increased crashes began over a week ago after the update was installed. Users have identified a common error message: "The driver detected a controller error on DeviceRaidPort1." A temporary workaround involving registry changes has been proposed by a community member, although no official response from Western Digital or Microsoft has been provided. Both companies are aware of the issue and are expected to release patches and firmware updates.

Some Western Digital SSDs cause Windows 11 crashes after 2024 update

Windows 11's 2024 update, 24H2, has caused system failures and Blue Screen of Death (BSOD) errors for some users, particularly those with specific Western Digital SSD models, namely the WD SN770 and WD SN580. The crashes occur after upgrading to the 24H2 update, displaying a “Critical Process Has Died” error. The issue may stem from faulty memory drivers managing the 200 Host Memory Buffers (HMBs) associated with these SSDs. Previous issues were reported with these models during the Windows 11 23H2 update. Users experiencing crashes are advised to disable HMB in the Windows Registry as a temporary workaround, although this may affect performance. Microsoft and Western Digital are aware of the issue and are working on a solution, but no official communication has been released yet.

Western Digital NVMe SSD users beware: Windows 11 24H2 is causing BSODs unless you tweak your registry | Tom’s Hardware

Since October 8, users of Western Digital NVMe SSDs, particularly the WD Blue SN580 and WD Black SN770, have reported persistent Blue Screens of Death (BSOD) following the Windows 11 24H2 update. This issue is linked to a misconfigured NVMe Host Memory Buffer (HMB), which has been observed to allocate up to 200MB instead of the intended 64MB, causing instability. A Registry edit can limit HMB allocation back to 64MB or disable it entirely, resolving the issue. Users of Western Digital SATA SSDs are not affected, and the problem may also impact other NVMe drives due to a misconfiguration in Windows 11. Some users have successfully reverted the Windows 11 24H2 update as an alternative solution.

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

Users of Western Digital's SN770 and SN580 SSDs are experiencing crashes and Blue Screens of Death (BSODs) after the 24H2 Windows update. The issue is linked to the Host Memory Buffer (HMB), as these DRAM-less SSDs store their mapping in system memory, and the update attempts to increase the HMB size from 64 MB to 200 MB, which is incompatible with the SSD firmware. Users have suggested workarounds, including modifying the Windows registry to disable the HMB or rolling back to the previous 23H2 version of Windows. Other SSD models with a 64 MB HMB have not reported similar issues, raising concerns about Microsoft's communication with SSD manufacturers regarding the update. Users are advised to wait for a firmware fix from Western Digital.
