METHOD_BUFFERED, FILE_READ_ACCESS | FILE_WRITE_ACCESS)
// #define DFP_RECEIVE_DRIVE_DATA 0x0007c088
#define DFP_RECEIVE_DRIVE_DATA CTL_CODE (IOCTL_DISK_BASE, 0x0022,
METHOD_BUFFERED, FILE_READ_ACCESS | FILE_WRITE_ACCESS)
#define FILE_DEVICE_SCSI 0x0000001b
#define IOCTL_SCSI_MINIPORT_IDENTIFY ((FILE_DEVICE_SCSI << 16) + 0x0501)
