When creating a forensic image using Imager, what happens automatically to the summary information file regarding Location and File Naming
Location - created in the same directory as the original image file.
File Naming - uses the same file name as the original image file with a .txt extension added.
True or False - FTK Imager includes write blocking capability to protect a drive during acquisition?
False - Although Imager is not included to make writes to a system, the Windows OS it runs on may still make writes. A hardware write blocker should be used whenever possible.
