SYMPTOMS

When you run the winsat.exe disk command on a computer that is running Windows 7, and filter drivers hook the DeviceIoControl function, you receive the following error message:
Failed to properly assess the disk. The parameter is incorrect.

CAUSE

This issue occurs because the async case is not handled when the Windows System Assessment Tool (WinSAT) tries to obtain the attributes of the raw drive by using the DeviceIoControl function.
