Orphaned vmdk is not listed using the script

Hi,

I am using this LucD's script to find the orpahed vmdks list. Script exists in the below URL.

http://communities.vmware.com/thread/266913

I ran this script on vCenter as well as directly on ESXi. The script runs successfully and list nothing except the Datastore.

But when i checked the Datastore, i found some of orphaned vmdks. Looking for help to get exact list.

For example I attached the screenshot.
