Detecting actual physical drive size

Is there a routine I can use to detect the actual physical drive size (including Non-formatted space!) of a drive?

I seem to recall the Win API report the formatted space but I need a routine/function that reports the actual physical size the drive was built for.

You need to use the API function DeviceIoControl and the IOCTL_DISK_GET_DRIVE_GEOMETRY command.

I assume this requires I write a device driver? Is there a non-device driver way to perform the same thing by any chance?

I looked up IOCTL_DISK_GET_DRIVE_GEOMETRY and found an example in the MSDN and it appears I do not need a device driver (phew!).

I neglected to mention I need a solution that works on Win9X platforms as well as NT and Win2K and IOCTL_DISK_GET_DRIVE_GEOMETRY is NT/Win2K specific.

Can you recommend a Win9x solution as well by any chance?

In addition to what jhance already suggested, 'IOCTL_DISK_GET_DRIVE_LAYOUT' might be an option, too...
