Hard disk interface used in computer forensic science

This paper will discuss a project that is related to the NIST development of standard methods for testing disk imaging tools. The goal of the project is to enhance current software-intensive tool tests by providing a hardware-oriented mechanism for simulating disk drive faults. This new system is significant because knowing the behavior of computer forensics tools operating in the presence of I/O errors is critical to a complete evaluation of disk imaging tools, and it is difficult to simulate hardware errors accurately with software alone.
