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

  • The reference for img flashing on Windows. Works well! But, on a multi-partition USB stick/SD card, it's unclear if it is flashing on the whole device or not.

  • Theres is a portable version? Thank you.

  • Works fine. Thank you.

  • Used to use this tool almost every day, it's very good indeed. But since I found it's modern, more feature rich alternarive (look for dotNet Disk Imager), I use only that. It has solved almost all bugs and added features requested for win32 disk imager.

  • Good tool! What I learned: - The tool does not keep Windows awake, so you need to turn off automatic Standby. (@developer: use SetThreadExecutionState...) - Do not use a microSD<->normalSD adapter when writing a (Raspberry Pi) image to the microSD. Use a USB adapter or card reader.
