Description

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.

Bear with us as we transition from launchpad.net.

    This review is for the 0.9 version only. This would have gotten 5 starts from me if it had not destroyed my boot drive. Before you dismiss me as a n00b that can't follow directions, I have been a systems programmer since the early 80's and I know what I am doing. There is a bug in this version that appears (based on other reviews) to rear its ugly head only occasionally. It hit me and had I not had a RAID mirror running I would be looking at a system rebuild. I downloaded a live (bootable) image for a USB, pointed to it with Win32DiskImager and selected the only drive in the drop-down (the E: drive) which was correct for the very high quality USB that was inserted and fully tested for read/write. When I chose Write (which copies the iso image to the USB) it looked like it was running nicely. USB was blinking and the system appeared to be working perfectly. Suddenly the PC went dark. I am running Windows 7 Professional. The system would not reboot. I rebuilt the damaged disk using my RAID mirror and was able to restore a working system, but -- if I did not have this I would be facing a major system rebuild. Other than that, this is a nice neat program that is simple to use. If I had not experienced this behavior on my system it would be part of my toolkit. I liked the ease of use enough that I might try it again one day - when it gets a version upgrade and I have a spare machine with which I do not mind experimenting. Until then I cannot even tell you how the support system rates because I will not try it again on this machine. I would have liked to see a better help system with clearer messages. Also, the Browse function took a long time to come up on my machine so there may be some issues where this is a telling condition. If you try this program, I would like to advise you to do so on a non-critical machine. If you have a Linux machine of any flavor it may be better to just use that and do a DD copy (make certain you choose the correct device).

    This software just overwrote my external USB hardrive, an 1TB WD MyBook.. First time I started it, it listed only my usbcard readers, second time, it listed only one usbcard reader, and my external drive (which was not listed first time), and selected the external drive first.. So beware of this thing.. And now I'm looking for something to rescue my drive..

    It warns that "writing to a physical device [a Kingston DT101 flash disk d:] may corrupt it" but what else is the purpose of the software? ...and then it goes on to corrupt the flash disk. So, not much use, then.
