Recently, some users reported instability problems in systems with SSDs da Western Digital e SanDisk after installing the update Windows 11 24H2. The good news is that the cause has been identified, and a fix is now available. The problem was related to the function Host Memory Buffer (HMB)and the solution came through a new firmware provided by Western Digital itself.
Which models are affected?
Incompatibility issues have been detected in specific SSD models, including:
- WD_BLACK SN770 NVMe SSD 2TB (WDBBDL0020BNC, WDS200T3X0E), firmware: 731130WD
- WD_BLACK SN770M NVMe SSD 2TB (WDBDNH0020BBK, WDS200T3X0G), firmware: 731130WD

Precautions
If you have one of the affected SSDs, but haven’t received the Windows 11 24H2 update yetthe recommendation is to apply the new firmware preventively. This will avoid instability issues in the future. It is worth remembering that the Windows Update may temporarily block the installation of the 24H2 update on PCs with these SSDs to avoid known issues.
If your system has already been updated to Windows 11 24H2 and is unstable, there is a temporary workaround that may help until the firmware is updated. The procedure involves the use of Registry Editor Windows to adjust the HMB allocation. To do this:
- Open the menu Starttype Regedit and right click on the corresponding result.
- Choose “Run as administrator”.
- Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStorPort.
- Create new value DWORD called HmbAllocationPolicyif it does not already exist.
- Double click on the value and set it to 2.
- Save the changes and restart the system.
This change should keep the system stable until the new firmware is installed. In some cases, setting the value to 0completely disabling HMB also temporarily solves the problem.
