Relating Volumes to partitions

Hi,

Background:

While trying to mount a partition in Windows Nt 4.0 the following
information was sufficient: Harddisk Number and Partition Number so that
the NT device name would be \Device\HarddiskN\PartitionM where N is disk
number and M is Partition number on that disk.

In Windows 2000, the NT Device names depends on Volume number. ie each
volume is \Device\HarddiskVolumeN where N is volume number. LDM does not
give the volume number so its difficult to mount a partition.

What I need:

I need to identify each volume in terms of partitions. i.e the mapping
should be:

\Device\HarddiskVolume1 = \Device\Harddisk1\Partition1 UNMOUNTED
\Device\HarddiskVolume3 = \Device\Harddisk0\Partition2 D:\Device\HarddiskVolume4 = \Device\Harddisk0\Partition3 E:\Device\HarddiskVolume2 = \Device\Harddisk0\Partition1 C:

Thanks in advance
