VMware Tools Shrink Option Unavailable?

In my recent post on using svMotion to reclaim disk space, I talked about using SDelete to zero out blocks for free space reclamation.  Another way to do this is to use the Shrink option which is part of the VMware Tools.  Duncan’s post here gives details on using the VMware Tools Shrink option so I won’t go into much detail, but it essentially accomplishes the same goal as SDelete.
