progress bar


dd is a command line tool to do byte-exact copy.


dd-gui is a simple GUI wrapper to enable you to easily launch dd without resorting to the command line. It will also show progress information throughout the copy.

Both source and destination can be either a system device from /dev or a file with the extension .img, for example: /dev/disk4, /files/dd.img
The app has only been tested on Mac OS 10.6.x


If you choose the wrong device as the destination, you can erase important data! Proceed with caution.
