It seems what you are asking: Is it possible to undelete/recover files from a vmfs formatted disk. In VMware 3.5 there was a vmfs-undelete that would allow you to undelete vmdk's that had been deleted off the disk. I heard it got removed in 4.x, and don't see it on my 4.1 box, but we may not have all the SDK's on that box.
I would say running something like DBAN on the drive would be prudent before letting it go out the door.
