If memory serves, you‘re looking for SHFormatDrive().
Use the Format method of the Win32_Volume class. Details here.

Sounds like you are looking for Disk Management Control Codes.
answered Oct 7 ‘10 at 11:10ThI have ended up using a combination of WMI & DeviceIoControl with the Disk Management Control Codes. This looks to be able to do everything that I want, except that currently I am having some issues with using the Win32_Volume Format method in C++, I am constantly getting a WBEM_E_INVALID_METHOD_PARAMETERS error. – Zac Shenker Oct 12 ‘10 at 4:36 https://stackoverflow.com/questions/3879294/windows-c-c-drive-init-partition-format
