FS-TST: Forensic Software Testing Support Tools Requirements, Design Notes and User Manual



James R. Lyle


This document describes FS-TST Release 1.0. A software package developed to aid the testing of disk imaging tools typically used in forensic investigations. The package includes programs that use the interrupt 13h BIOS disk interface to initialize disk drives, detect changes in disk content, compare pairs of disks, and simulate bad sectors on a disk. Most of the software is written in Borland C++ 4.5 with a few parts written in Borland Assembler. The software can be used in the DOS 6.3 environment to setup disk drives for tests, measure the results of a test and aid in documenting test runs. The intended audience for this document should be familiar with the DOS operating system, computer operation, computer hardware components such as hard drives, hard drive interfaces (e.g., IDE or SCSI) and computer forensics. A working knowledge of C and Assembly programming is not necessary for understanding but would be helpful. The package can be obtained from the WWW at the HTTP://WWW.CFTT.NIST.GOV web site.
