Partition information of a volume

NTDEV
1

Hi,
is there any way to find the partition number and disk of a given
volume(partition). I want this on a system which runs either NT or 2K. On 2K
it is not a dynamic volume or Ft volume from NT. The volume is just a simple
partition or logical drive. Is there any way to get the information about
the offset of a volume(partition) on the disk.Any help is greatly
appreciated.

Thanks in advance,
Nagesh Bhattu

I found a way for this,
There is an IOCTL “IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS” available on
Windows 2000 which will retrieve this information. The SDK documentation
says that this is limited to windows XP and .NET server. But works fine on
all windows 2000 platforms.There is a tool on sysinternals.com which will
use this IOCTL to fetch this information
http://www.sysinternals.com/ntw2k/source/misc.shtml#diskext. It confirms
that though the SDK document says the availability of this IOCTL only in XP
and .NET server it works fine with all WIN2K platforms.

use the “IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS”, by passing the handle to the
volume of interest…it takes a strut of “volumediskextent”, which
interanlly takes “diskextent”, which gives u theofset fromt he starting of
the disk and also the disk no. in which it is found…

trust this helps uo ut.
