An alternative to dd for writing images to sd-cards

Project Description

wrimg is an alternative for dd to write images to removable media. It has the following advantages:

  • Syncs buffers after each chunk is written, allowing C-c to work
  • For the same reason wrimg can make accurate predictions about the remaining time
  • Automatically adjusts buffer size when copying
  • Contains extra safety-checks to keep you from accidentally erasing your hard drives!

It is slightly slower than dd, with common SD-card/USB data rates usually a second or two. Copying between two very fast devices (like SSD-to-SSD) is better left to dd.


wrimg can be installed from PyPI:

$ pip install wrimg


Usage is straightforward:

$ wrimg someimg.iso -t /dev/sdX

The --target/-t can be omitted, causing wrimg to display a menu of suitable targets. For other options, check the --help option.
