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.

    Used this Software to write a image file to my 2Gb SHDC chip on a USB 2.0 Micro SD Card Reader on a Dell XPS17 Win7 Ultimate SP1 64Bit OS. At the same time I had attached 2x USB 3.0 WD My Passport 2TB Model WD20NMVW Hard Drives loaded with 2 Year of supper important work. One formatted as Fat32 and the other with the same Data as a Backup on a NTFS File format. After using Win32 Disk Imager Release 0.9 for Windows to write the *.3ds file to the Flash Drive it did perform this task well but at the same time it did also format the other two attached USB 2TB WD Drives. Now 2 days later after using all kind of Partition and File Recovery Software such as EaseUS Data Recovery Wizard Pro or Stellar Phoenix Windows Data Recovery Pro or Paragon Partition Manager 12 Pro or Hirens 15 Boot DVD, I still haven't been able to recover the Data. I didn't touch or install the Drives since I won't risk to lose more. It took Win32 Disk Imager Release 0.9 less than 10 sec to erase all and I assume it must be some kind of Partition Table or Root Sector such as a Quick format type thing, but the data must me there. So my hint is, if you use this Software disconnect any other US Drive. It also doesn't show the 3ds content before writing it would be a nice feature. Any tips greatly welcome...
