You're using the wrong structure type with IOCTL_DISK_SET_PARTITION_INFO_EX. Please give a link if someone is aware of one. The above sample is for MBR partition style only. If we comment out the last call, the disk is being initialized as raw disk, But this won't meet our requirements.

Got the following code snippet by searching a bit //To open the drive We are using DeviceIoControl() method and IOCTL_DISK_CREATE_DISK, IOCTL_DISK_SET_DRIVE_LAYOUT_EX, IOCTL_DISK_SET_PARTITION_INFO_EX codes from Disk management control codes to make the disk available for use.
Initialize drive with diskpart windows#
We are trying to initialize disk with the properties of some existing disk on Windows server 2008/2012 through a C++ program.
