Simple Forensic Puzzle #1

I recently had a need to make some simple forensic images for use with students. I decided to make one with some simple "anomalies" in hopes the students would pick up on them. So I figured I would share them and let others take a look to help refresh some foundational examination techniques.

The image linked below if fairly simple. A few files, not much more. But there are a few "anomalies" that should be detected and noted.

  1. Not sure if I am on the right track, but here are a couple of things:

    MBR partition table shows only 07 and one 06, but there are actually one 07 and two FAT 16's.

    Relative position for 07 and 06 is the same: 1024000.

    Size for 06 is zero.

    Sector 63 does not have volume boot record.

    Volume C and D appear to be almost identical, except the FAT for the D volume is about four times the size of C's FAT.

    Lastly, volume E's $Bad Cluster is about 524MB, seems too large.

  4. I see a discrepancy in the volume file system and the partition ID as shown in the MBR.

    C volume file system is FAT16 but MBR shows 0c (FAT32x)
    D volume file system is FAT32 but MBR shows 07 (NTFS)
    E volume file system is NTFS but MBR shows 06 (BIGDOS)
