A disk image should be made prior to performing any forensic analysis of the disk. Creating a disk image is important in forensics for several reasons:
+
An executable file is used to perform tasks according to encoded instructions. Executable files are sometimes also referred to as binaries which technically can be considered a sub class of executable files.
  
1. Ensure that disk information is not inadvertantly changed during analysis. 
+
There are multiple types of executables:
 +
* Scripts
 +

 +
* DOS, Windows
  
2. By performing an original disk image and storing the original disk, it is possible to reproduce forensic test results with an exact reproduction of analysis methods on the original evidence.
