A person before me decided to make VHD for Hyper-V and made them with a ridiculous amount of space. One of them is at 90GB (HD Space). I want to resize them that one to about 20GB. So I used VHD Resize. It resized the HD to 19.53 GB. Now the problem is the space that it took away is listed as unallocated space, which is still keeping the .vhd file size at 51GB. Is there anyway for me to remove that unallocated space so I can get the .vhd file size down?
