I have created a VM with a expanding VMDK set to a 500GB, however, I want to change the size of the VMDK to 40GB, is that possible?

I have searched solutions but most of it are just "compacting" the VMDK (I mean removing fragments) and also expanding the VMDK, but none for my requirements.

VMware Converter Standalone will let you change the hard drive from thin provisioned to flat (full size allocated). This will create a VM with a 500GB disk, however.

You can use a Linux LiveCD with GParted to resize the partition, however you don't mention the OS, but procedure varies depending on the partition type.

I assume you mean to use the partition program inside the VM right? But that would only affect the partition; as far as the guest system (BIOS) is concerned, the drive is still the same size as before because that is what the VM software is telling it. – Synetech Jul 13 '12 at 1:06
