What is Win32 Disk Imager?

Win32 Disk Imager is a free program designed for writing a raw disk image to a removable device (USB flash drive, CD, DVD, etc) and backing up removable storage device to an image file in Windows.

It is an open-source tool, so any one who has programming experience can branch and modify it. The latest version is available for Windows 10/8/7. If you are running older Windows like Windows XP or Vista, you can download the previous release.

Why do you need an alternative to Win32 Disk Imager?

Win32 Disk Imager software is quite easy to use for removable drives. However, there are some issues reported. Some users find Win32 Disk Imager fails with an error message like “Cannot find the device”, “Error 5: Access is denied”, and “Error 2: The system cannot find the file specified”. In such cases, you may get an alternative to work around.

Besides, if you intend to backup your removable devices into an image file regularly, you probably are not content with Win32 Disk Imager utility. That’s because the more advanced options like automatic backup, incremental backup and real-time sync are missing in Win32 Disk Imager.
