You need to design a CASE for other student to investigate. As an example; at the end of this week you should generate the following materials: A case description. For example, what kind of suspect you have, and what kind of potential criminal activities the suspect may have committed? Generate some potential files (you may delete or overwrite etc.) on a floppy drive or a small size USB memory stick (the image could be huge if you use a big USB memory stick). Use some tools discussed in the VirtualTools message to make a bit-by-bit image of your floppy image. Though you can delete and do any kind of activities, it is important that you should have some traces for other students to find the evidence on your image in next week. For your reference, you may follow the styles in https://dftt.sourceforge.net/ for your case image generation. Since many laptops do not come with floppy drive, you may work on a virtual floppy drive (that is, all software based images). Some tools are discussed in the VirtualTool message.
