Disk on VM.

I need to shrink D:\ drive on my VM. It was build with thick provisioning.

1. Run shrink through VMWare Tools;
2. Shrink volume (20GB) and deleted space through Server Disk Management.

Still cannot change a size of my D:\ drive through Edit Settings on my VM.
Is it even possible to do so without doing V2V?

Do you mean you need to reduce the size inside the guest OS? If so, what is that OS? If Windows 7 or Windows 2008 you can use it's diskmanagement to reduce the size of partitions. If the OS is another, it depends, you may have to use a 3rd party tool from which you boot the VM from, like the PartedMagic LiveCD:

Thats the only common way to do. You need only to migrate the vmdk to the new datastore file and after delete the old bigger one.

Or you use a third party tool like Easeus Partition Master to shrink first on base of the os and after the vmdk.
The simplest way is to use the volume to volume copy. It's reasonably fast, and it defrags the files if you can get away with a file copy approach.

I've also done this by creating a new disk, not partitioning it, and using one of the many disk copying programs, the one I use is Norton Ghost disk copy.

You can't really change the size of the disk in the settings area.
