Query: This is a DOS application

Even though Drive Image allows you to set up parameters in a Windows interface it is actually a DOS program, the disk image reboots in DOS mode and runs in DOS. Unfortunately if you want to create your disk image on a USB device, such as an external USB disk, The windows drive letter isn't known by DOS. So when Drive Image reboots you in DOS it fails. In my case it actually froze; so I had to manually reboot to get back to windows.Since this is a DOS application & there are a lot of removable USB based storage options available, this DOS based application is basically obsolete. Save your money , DOS is dead.
