Since first install 24H2, BSOD's with Western Digital NvME SN560

I'm getting random BSOD's with Windows 11 Pro on my Asus Vivobook 15.

I'm wondering if it's connected to the Western Digital HMD problem.

I have a NvME WD PC SN560 which came installed with the laptop.  Since 24H2 has been installed, nothing but random BSOD's several times a day.  The laptop completely freezes, then a BSOD with "Critical Process Died 0xEF"

appears for a second on screen.  The laptop then automatically shuts down, restarts and boots immediately into the BIOS screen.  The BIOS screen states that there is no SSD installed.  Restarting the laptop from this boot screen, the laptop again boots up to the BIOS screen and states no SSD is installed.  On holding down the on/ off button of the laptop when in the BIOS screen, the laptop will the shut down from the BIOS screen and reboot.

The laptop then reboots, Windows 11 then loads normally.  Once booted into Win11, it's only a question of time before a random BSOD appears again.

There is no Western Digital update for my SN560 to fix this problem, as there is for WD SN580 and SN770 SSD's.  There is also no BIOS update available for my Asus Vivobook 15 x1505.

I've just tried the known registry hack for this problem to see if it resolves the random BSOD issue.

Use the Windows Registry Editor (Temporary Workaround) If you cannot update the firmware right away, you can disable or limit HMB to prevent BSODs.

Open Registry Editor: Press the Windows key + R, type regedit, and press Enter.

 Navigate to the key: Go to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\stornvme\Parameters\Dev

ice.

Create the value:

Right-click in the right-hand pane and select New > DWORD (32-bit) Value.

Name the new value HMBAllocationPolicy.

 Set the value data:

Double-click the new HMBAllocationPolicy value.

Set its Value data to 0 to disable HMB, or to 2 to limit HMB to 64MB.

Click OK & reboot.

If that does not fix the problem, I'll be forced to RMA the laptop. Luckily, my warranty lasts until 2 April 2027.
