Something new: dcfldd – a more advanced dd for data transfer

Aug 30 2013 Published by under howto

Today I discovered dcfldd, and it was right there in Debian already: apt-get install dcfldd.

This was while building up a new Raspberry Pi image for a project I have in mind.

Specifically, dcfldd provides a progress meter, unlike the ubiquitous dd command. It also appears to be aimed at forensics and advanced data recovery, featuring on the go hashing of data as well.

You can use dcfldd to write an image onto an sdcard in exactly the same way as dd:

dcfldd bs=4096 if=2013-07-26-wheezy-raspbian.img of=/dev/sdl

Sample Progress Output:

141568 blocks (553Mb) written.

It looks like you can get a Windows binary as well.
