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.

    I have used this Program to install Kali Linux from a USB-Stick. I thought it would work like YUMI (It would only add the input of the Kali.iso), but it has formatted my hole drive. I know how to work with a Computer, but a little warning Screen wouldn't be bad!!!

    Selecting .iso files not intuitive. Messages before burn about making the USB device are scary. Decided not to use because I like mys USB devices to last for a little while at least

    On a Macbook Air with Windows 7 pro, it always gets up to a percent (I think around 70%) then it stops, tried man times, it doesn't fail immediately, so that you time is always wasted. On a Lenovo Thinkpad the backup was created properly, I am not sure how reliable the restore is.

    version 0.9.5. sobre win 8 64 bits. Me dejo inservible un pendrive de 8GB, no se puede formatear, cambio la capacidad. Volví a pasarle la misma versión con otra imagen distinta y dijo q escribió todo y lo mismo no lo lee, ni en el explorador de archivos ni booteando desde el pendrive. No solo no me sirvió para lo q quería sino q me daño el pendrive. Actualización: Use el EaseUS Partition Master Free para eliminar particiones y dejar el tamaño original del pendrive. Actualización2: Me aclararon algo q suponía, no es error del programa y tampoco me dejo inservible el pendrive. Sino que el programa al grabar la imagen raw modifica la tabla de particiones ( Para volver a usar el pendrive no alcanza con un formateo, sino hay q armar de vuelta la tabla de particiones para usar el pendrive con toda la capacidad. Además la no lectura del contenido grabado en el pendrive era por no instalar los drivers necesarios para leer particion ext3 en Win8 que era lo q contenía la .img grabada. Me parece muy baja la clasificación que había puesto así q la subo. Gracias por su respuesta.
