AMD SCSIAdapter 9.3.0.221 update is crashing Windows 10 PCs

If you see the “Advanced Micro Devices, Inc. — SCSIAdapter — 9.3.0.221” driver when you check for updates today, immediately hit the brake on Windows 10 updates. Microsoft has rolled out a new driver that could affect the functionality of certain AMD hardware, users are reporting.

According to numerous reports, SCSIAdapter — 9.3.0.221 has a nasty gremlin that causes a PC to crash with a Blue Screen of Death error code “INACCESSIBLE_BOOT_DEVICE”. As a result, Microsoft has pulled the driver update from the Windows Update, according to a support staff who wished to remain anonymous.

As a result, some folks have started getting the update on the production builds of Windows 10.

“Yesterday, Windows Update automatically installed Advanced Micro Devices, Inc. — SCSIAdapter — 9.3.0.221. After I rebooted, it repeatedly failed to turn on, with an INACCESSIBLE_BOOT_DEVICE error until it eventually entered WinRE and repaired itself,” a user wrote in the Feedback Hub.

“Windows Update installs the following driver: Advanced Micro Devices, Inc. — SCSIAdapter — 9.3.0.221, and after rebooting the system enters in GSOD loop with the INACCESSIBLE BOOT DEVICE error. The only way to recover the system is booting into Windows Recovery Environment and doing a Startup repair,” another user noted.

According to reports seen by us, the bug seems to be hitting select AMD configurations only, particularly the PCs with GIGABYTE X570 motherboard.
