I dont understand when we have to find the dummy files
Originally posted by another user

Open your MasterImage+Dummy_To_Decrypt_xxx.bin file in WinHex (You must login or register to view this content.) and seek for a dummy sector; it's easy to understand where the dummy starts,
all of the dummy sectors are equal in size (1 sector is 512 bytes). You just have to seek the entire HDD scrolling it down until you see a
repetitive pattern different from the initial one (a fast method is to go at the middle of the .bin file, there should be the dummy).

- Note: Set Winhex this way: VIEW > RECORD PRESENTATION: put the 'v' in all 3 checkmarks, then fill these values:
First Record at offset: 0
Record size in bytes: 512

- Remember to select a good background color in WinHex options (Options > General) or you won't notice where a sector starts!
This way each sector will be displayed in an alternate color, making it easier to see different sectors.


What does it mean ? How is the dummy ? I dont know what I am looking for. Please explain me...
I rep+ for a good awnser Claps

Ok here is how i did it. Download hex editor neo and open up master image + dummy. Now open up your master image to encrypt in hex editor neo also. Now under one of the menus is compare files and it will show results. The data not found in the master image to encrypt is the dummy file

The first 16 bytes is what you use. Two letters or numbers equals a byte so you need the first 32 letters and numbers
