Win32 Disk Wipe Utility.
Currently a work in progress.
Right now everything is hard coded. Update your drive letter in the main.cpp file to the drive letter you want wiped.
LPWSTR driveToOpen = L"\\\\.\\G:"; // <--- change drive letter
If you run the program it will start wiping the disk with 0x33333333 for every 4 bytes. It will convert the disk to RAW.
