Previously cases of BSOD were reported in Windows 11 24H2 with some SSDs. Now WD has added Sandisk models, Microsoft has rolled back the update for them, and WD has released a fix.
Following user reports of problems with WD SSDs, there was evidence of problems with Sandisk SSDs as well. Microsoft confirmed that it was blocking updates for some users with certain SSD models.
«Microsoft is blocking systems with affected models from upgrading to Windows 11 24H2 until the firmware is updated».
As a reminder, some SSDs may need up to 200 MB of system memory buffer, and Windows 11 23H2 has dealt with this properly by offering only 64 GB. Windows 11 24H2 started providing 200 MB as required by SSD specifications, but it causes a «blue screen of death.
Sandisk / WD has already released the appropriate SSD firmware. You can update through the proprietary Western Digital Dashboard utility, under «Tools» to see if a firmware update is available. If so, click on it. Nothing should happen to your files, but it is recommended to make a backup just in case. Here are the SSD models officially recognized as problematic:
- WD_BLACK SN770 NVMe SSD 2 TB
- WD_BLACK SN770M NVMe SSD 2 TB
- WD Blue SN580 NVMe SSD 2 TB
- WD Blue SN5000 NVMe SSD 2 TB
- SanDisk Extreme M.2 NVMe SSD 2 TB
The Windows registry fix we published earlier also helps with the blue screen. You can use it if the BSOD occurs with drives from other manufacturers (this is not impossible). There is also another way:
1. Enter the following code in «Notepad»:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorPort]
"HMBAllocationPolicy"=dword:00000002
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\stornvme\Parameters\Device]
"HostMemoryBufferBytes"=hex(7):56,00,45,00,4e,00,5f,00,31,00,35,00,42,00,37,00,\
00,5f,00,35,00,30,00,34,00,31,00,26,00,52,00,45,00,56,00,5f,00,3f,00,3f,00,\
20,00,36,00,37,00,31,00,30,00,38,00,38,00,36,00,34,00,00,00,00,00
2. Save and create as a registry file, for example SSD.reg
3. Double-click on the file, follow the on-screen instructions, and restart your computer.
Interestingly, Windows 11 24H2 has been in limited availability for a year, and Microsoft and WD could have dealt with the problem earlier, not after the public release of the update.
