Subject: [ros-dev] why IOCTL_DISK_GET_DRIVE_GEOMETRY_EX failed in windows 2000?

hi,guys:

I don't know if it is proper to ask such a question here. I'm sorry if I break some rules.

why IOCTL_DISK_GET_DRIVE_GEOMETRY_EX fail in windows 2000 and succeed in windows xp and greater version?

or how can I get a disk(whatever,ATA,SCSI,USB )'s real size(including additional sectors) in a easy way in windows 2000, just like there is such a function,

__int 64GetDiskRealSize(HANDLE hDisk);

Could anybody help me?

Waiting for reply.

Thank you!
