f3 - Fight Flash Fraud
f3 is a simple tool that tests flash cards capacity and performance to see if they live up to claimed specifications.
F3 stands for Fight Flash Fraud, or Fight Fake Flash.
Table of Contents
Examples
Testing performance with f3read/f3write
Use these two programs in this order. f3write will write large files to your mounted disk and f3read will check if the flash disk contains exactly the written files:
$ ./f3write /media/michel/5EBD-5C80/ $ ./f3read /media/michel/5EBD-5C80/
Please replace "/media/michel/5EBD-5C80/" with the appropriate path. USB devices are mounted in "/Volumes" on Macs.
If you have installed f3read and f3write, you can remove the "./" that is shown before their names.
Quick capacity tests with f3probe
f3probe is the fastest drive test and suitable for large disks because it only writes what's necessary to test the drive. It operates directly on the (unmounted) block device and needs to be run as a privileged user:
# ./f3probe --destructive --time-ops /dev/sdb
Warning
This will destroy any previously stored data on your disk!
Correcting capacity to actual size with f3fix
f3fix creates a partition that fits the actual size of the fake drive. Use f3probe's output to determine the parameters for i3fix:
# ./f3fix --last-sec=16477878 /dev/sdb
Installation
Download and Compile
The files of the stable version of F3 are here. The following command uncompresses the files:
$ unzip f3-7.1.zip
Compile stable software on Linux or FreeBSD
To build:
make
If you want to install f3write and f3read, run the following command:
make install
Compile stable software on Windows/Cygwin
If you haven't already, install the following Cygwin packages and their dependencies:
- gcc-core
- make
- libargp-devel
To build, you need special flags:
export LDFLAGS="$LDFLAGS -Wl,--stack,4000000 -largp" make
If you want to install f3write and f3read, run the following command:
make install
Compile stable software on Apple Mac
Using HomeBrew
If you have Homebrew already installed in your computer, the command below will install F3:
brew install f3
Using MacPorts
If you use MacPorts instead, use the following command:
port install f3
Compiling the latest development version from the source code
Most of the f3 source code builds fine using XCode, the only dependency missing is the GNU C library "argp". You can build argp from scratch, or use the version provided by HomeBrew and MacPorts as "argp-standalone"
The following steps have been tested on OS X El Capitan 10.11.
Install Apple command line tools:
xcode-select --install
See http://osxdaily.com/2014/02/12/install-command-line-tools-mac-os-x/ for details.
Install Homebrew or MacPorts
HomeBrew:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
See https://brew.sh/ for details.
MacPorts: https://www.macports.org/install.php
Install argp library:
brew install argp-standalone
See http://brewformulas.org/ArgpStandalone and https://www.freshports.org/devel/argp-standalone/ for more information.
Or, for MacPorts:
port install argp-standalone
See https://trac.macports.org/browser/trunk/dports/sysutils/f3/Portfile for more information.
Build F3:
When using Homebrew, you can just run:
make
When using MacPorts, you will need to pass the location where MacPorts installed argp-standalone:
make ARGP=/opt/local
The extra applications for Linux
Install dependencies
f3probe and f3brew require version 1 of the library libudev, and f3fix requires version 0 of the library libparted to compile. On Ubuntu, you can install these libraries with the following command:
sudo apt-get install libudev1 libudev-dev libparted0-dev
Compile the extra applications
make extra
Note
- The extra applications are only compiled and tested on Linux platform.
- Please do not e-mail me saying that you want the extra applications to run on your platform; I already know that.
- If you want the extra applications to run on your platform, help to port them, or find someone that can port them for you. If you do port any of them, please send me a patch to help others.
- The extra applications are f3probe, f3brew, and f3fix.
If you want to install the extra applications, run the following command:
make install-extra

Graphical User Interfaces
Thanks to our growing community of fraud fighters, we have a couple of graphical user interfaces (GUIs) available for F3:
F3 QT is a Linux GUI that uses
QT. F3 QT supports f3write
, f3read
, f3probe
, and f3fix
. Author:
Tianze.
F3 X is a OS X GUI that uses
Cocoa. F3 X supports f3write
and f3read
. Author: Guilherme
Rambo.
Please support these projects testing and giving feedback to their authors. This will make their code improve as it has improved mine.

changelog - Change log for package maintainers f3read.1 - Man page for f3read and f3write In order to read this manual page, run `man ./f3read.1` To install the page, run `install --owner=root --group=root --mode=644 f3read.1 /usr/share/man/man1` LICENSE - License (GPLv3) Makefile - make(1) file README - This file *.h and *.c - C code of F3
Bash scripts
Although the simple scripts listed in this section are ready for use, they are really meant to help you to write your own scripts. So you can personalize F3 to your specific needs:
f3write.h2w - Script to create files exactly like H2testw. Use example: `f3write.h2w /media/michel/5EBD-5C80/` log-f3wr - Script that runs f3write and f3read, and records their output into a log file. Use example: `log-f3wr log-filename /media/michel/5EBD-5C80/`
Please notice that all scripts and use examples above assume that f3write, f3read, and the scripts are in the same folder.
