Use the System.IO namespace, instantiate a DriveInfo class, enumerate the
logical drives, select the one you want, and get the drive’s information.

You can’t use this IOCTL in Windows Server 2000. Windows supports IOCTL_DISK_GET_LENGTH_INFO since XP. For Win 2000 you could use IOCTL_DISK_GET_DRIVE_GEOMETRY. This IOCTL returns DISK_GEOMETRY struct which contains information to get a length of a disk.

IOCTL_DISK_GET_PARTITION_INFO the PartitionLength field.

It is also faked and works for Dynamic Disk volumes.
