DDriveWrite is a C#.Net project that facilitates direct reading and writing of a disk image to a disk drive in a manner not unlike a *nix 'dd' command to a drive device node.
Designed for use in bootable USB image applications.
Update: After about 2 years I've finally made a couple small updates, improving usability on more modern versions of windows.
This is a small utility tool that will help you format and create bootable flash drives for Windows 7/8 . It can be useful if you want to create installation media from bootable ISOs and if you want to install Windows7/8 on a system that doesn't have a CD-ROM device installed .
