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.

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.

User Reviews

  • I often use it to create images of Raspberry Pi. I made a Japanese pm file with gratitude.

  • Doesn't work for me. It makes the USB unserviceable. It format the drive, as supposed, but it also removes the partition. I had to recreate the partition table and use unetbootin.

  • Excellent Software.

  • NOT BRICKED: your USB is was and never will be bricked unless youre too stupid to read... you need to use dd to write another file table after using the drive as a boot device. YOURE A FUCKING IDIOT LERN2GOOGLE YOU MORON

  • Works sometimes, did corrupt about three USBS which I had to chuck out because they were f**ked, THIS ISSUE NEEDS TO BE FIXED.
