Corrupted GPT Partition Table on ESXi 5.0 VMWare Hypervisor VMFS

We have an ESXi 5.0 VMWare Hypervisor VMFS Partition whose GPT partition table is corrupted so when we access the host we see the VM Guests showing "Unknown". We don't know the previous values of the VMFS partition (start/end sector). How can we extract the vmdk files from the corrupted partition to add them to our backup ESXi 4.1 host?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I would suggest contacting VMware Support or Kroll Ontrack Data Recovery if you do not have a backup, and the virtual machines and data are important.
