F3 - Fight Flash Fraud for Windows

This is a Windows port of the popular F3 (Fight Flash Fraud) tool, which helps detect counterfeit flash drives and memory cards.

Overview

Counterfeit flash drives are common in the market - these drives report a larger capacity than they actually have. F3 provides tools to test if your USB flash drive or memory card is genuine.

This Windows port includes three main tools:

• f3write: Writes test files to the flash drive
• f3read: Verifies test files written by f3write
• f3probe: Directly probes the device at a hardware level (requires admin privileges)

Pre-compiled Binaries

For convenience, you can download pre-compiled Windows binaries from the Releases section of this repository.

Building from Source

Requirements

• MinGW-w64 (for Windows builds)
• GCC (for Linux/WSL builds)
• Make

Building on Linux/WSL for Windows

1. Clone the repository:

   git clone https://github.com/crack666/f3-windows-port.git
   cd f3-windows-port
   

2. Run the build script:

   chmod +x build-win.sh
   ./build-win.sh
   

3. The Windows executables (*.exe) will be created in the current directory.

Building Directly on Windows

1. Install MinGW-w64:

   • Download from MinGW-w64 or install using MSYS2
   • Add MinGW bin directory to your PATH

2. Clone the repository or download the source files

3. Compile the source files:

   gcc -std=c99 -Wall -o f3write.exe f3write-win.c
   gcc -std=c99 -Wall -o f3read.exe f3read-win.c
   gcc -std=c99 -Wall -o f3probe.exe f3probe-win.c
   

Usage

Basic Flash Testing (f3write/f3read)

1. Write test files:

   f3write.exe J:
   

   This will fill drive J: with test pattern files. You can also specify how many MB to write:

   f3write.exe J: 1000
   

2. Verify test files:

   f3read.exe J:
   

   This reads back the test files and checks if they're intact. If any corruption is detected, the drive may be counterfeit or damaged.

Advanced Hardware Testing (f3probe)

f3probe.exe J:

For more thorough testing (may overwrite data):

f3probe.exe --destructive J:

Note: f3probe requires administrator privileges and direct access to the drive. Some security software or write-protection mechanisms may interfere with its operation.

Batch Testing

You can use the included batch files for easier testing:

• f3-test.bat J - Runs f3write and f3read on drive J:
• f3probe-test.bat J - Runs f3probe on drive J:

Creating a Release

To create a release with pre-compiled binaries:

1. Build the executables following the instructions above

2. Create a ZIP archive containing:

   • f3write.exe
   • f3read.exe
   • f3probe.exe
   • f3-test.bat
   • f3probe-test.bat
   • README.md
   • README_WINDOWS.txt

3. Upload the ZIP file to the GitHub Releases section of this repository

Limitations

This Windows port has some limitations compared to the Linux version:

1. f3probe may have limited functionality on some systems due to Windows' restrictions on direct disk access
2. f3fix and f3brew (Linux-only tools) are not available
3. Performance may vary compared to the Linux version

Technical Details

The Windows port was created by:

1. Cross-compiling the f3write and f3read tools with MinGW
2. Reimplementing f3probe for Windows using direct disk access
3. Ensuring compatibility with Windows' file and path conventions

Warning

• Always backup your data before testing drives with f3probe's destructive mode
• Be sure to run Command Prompt as Administrator when using f3probe
