SYNOPSIS



f3write [--start-at=NUM] [--end-at=NUM] <PATH>
f3read  [--start-at=NUM] [--end-at=NUM] <PATH>



DESCRIPTION

F3 (Fight Flash Fraud or Fight Fake Flash) tests the full capacity of a flash card (flash drive, flash disk, pendrive). It writes to the card and then checks if can read it. It will assure you haven’t been sold a card with a smaller capacity than stated.

When writing to flash drive, f3write fills the filesystem with 1GB files named N.h2w, where N is a number (i.e. /[0-9]+/).

WARNING: all data on the tested disk might be lost!

OPTIONS

--start-at=NUM
  Initial number of file names. Default value is 1.
--end-at=NUM
  Final number of file names. Default value is "infinity".

EXAMPLE

To write over a flash drive mounted at /media/TEST:



      $ f3write /media/TEST

To read this flash drive:



      $ f3read /media/TEST
