To create a bit-stream image of a physical storage device, FTK Imager needs low-level access to the operating system's kernel. It achieves this by installing and running a temporary kernel-mode device driver (typically named adforensic.sys or similar, depending on the version).
This error completely halts the imaging or analysis process. Fortunately, it is a known issue usually tied to Windows security protocols, driver conflicts, or user permissions. This comprehensive guide breaks down exactly why this error happens and provides step-by-step solutions to fix it. Why Does This Error Occur?
