This program is designed to write a raw disk image to a removable device or backup a removable device to a raw image file. It is very useful for embedded development, namely Arm development projects (Android, Ubuntu on Arm, etc). Anyone is free to branch and modify this program. Patches are always welcome.

Warning: Issues have been reported when using to write to USB Floppy drives (and occasionally other USB devices, although very rare). It is highly recommended that before an image is written to a device, the user should do a Read to a temporary file first. If this fails, please report the failure along with your system information (file a new bug, NOT a review).

Please do not use the reviews area for questions or bugs, as I have no way of responding to them.

    This program is fantastic. I was taken aback by how difficult it was to find a Windows program specifically to write .bin images to a USB drive, but this one does it beautifully. This was the answer to several workdays of headache. Very minimalistic UI, but chances are you're already familiar with image writing software capabilities - that's why you went out looking for this program in the first place!

    Excellent program. Simple and in working state, just what I need.

    This is really useful software for us. We do software development and we have scripts that generate linux filesystem images automaticaly and we make them available on an internal web server. People using windows machines can access the web server to download the linux filesystem image and use Win32DiskImager to write the linux filesystem image to a USB memory stick. They can then use the USB memory stick to update the embedded linux system we're in the process of developing. This software is great for us and has never given us any problems. We're currently using v0.8. There are a couple of feature request that would make it even better for us: first, the ability to verify that the image written to the USB memory stick has been correctly saved, and secondly, the ability to erase and reformat the USB memory stick after use so it can be used on windows again.
