We are running a win 2008 core host in a HyperV role. We have expanded the logical drive on a RAID 1+0 array belonging to the server, as we needed more space.

We have two data partitions D: and E: I want to expand them both so they use all space, and are equally sized. There is data on all partitions, although E is not in live use (so files can be moved and copied from it.

Current: Current partition map

What I want- temporary Partition (F:) at end of drive:

Proposed map with offset and new part at end

I am going to create a temporary partition F: so I can move the files from E: onto it, then delete E:, expand D: to the desired size, then rename F: to E: To do this I need to create F: from the end of the drive, ie. have unused space between E: and F:

tl;dr How do I create a partition with a large offset in Windows server?
