DownloadThis 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.
This release is for Windows 7/8.1/10. It will should also work on Windows Server 2008/2012/2016 (although not tested by the developmers). For Windows XP/Vista, please use v0.9 (in the files archive).
Warning: Issues have been reported when using to write to USB Floppy drives (and occasionally other USB devices, although very rare). While this has been fixed in v1.0, 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.
Known issues:
Currently, the program will crash if you are using a Ramdisk. This is being debugged.

Trash. It turned my 512gb SD card into a 15gb. Took an hour to find a fix. Here is a link to a youtube video for the fix for anyone who has the unpleasentness of using this trashware. youtube.com/watch?v=aPEEpHqq40c

Fine tool

For those of you having the problem with Win32 re-writing your SD cards as mb instead of gb.. I had this problem too. I found that I could recover them by formatting them in a digital camera. After that, you can format them on your computer and then run them through win32 again.

It destroyed 2 SD chips and an SSD before I realized what the problem was. In each case, it wrote them as 100 MB (mega, not giga) and it was impossible to reformat them to something better. Well, maybe I will find some other prog like Linux dd can fix them, but for the moment they are dead media. The UI was all messed up, too. Running on Windows11. I should have heeded the warning signs of something that might be trouble. It was. Find something better.

The program did not work. I ran the verify on two USB flash drives and it said OK. Neither worked. I got a message no boot sector. Windows said that both devices were unformatted.
