I'm not asking a official document to tell me, hi dude, Minimum supported client of IOCTL_DISK_GET_DRIVE_GEOMETRY_EX is Windows XP, it is not supported by W2k, I asked the question here because I wanna to know the fundamental "why".
Because Windows XP is not Windows 2000. Just like Windows 2000 doesn't have themes but Windows XP does. Why?
The question is why you need IOCTL_DISK_GET_DRIVE_GEOMETRY_EX, when Windows 2000 implements IOCTL_DISK_GET_DRIVE_GEOMETRY, which is largely identical except for (surprise surprise) features implemented in Windows XP
