Hyper V VHD Disk Corrupt

We have an SBS 2008 running as VM inside Hyper V. The Hyper V is run by a physical Win 2008 Stnd editihe SBS 2008 has 2 vhd drives, 1 being the OS and the second being the data disk. All of a sudden the data vhd is saying that it's a new drive with unallocated space inside the SBS 2008 machine. When you go back into Hyper V management console and inspect the vhd it says it's only 11 Meg in size yet it was 160 GIG in size!! All our data was on that vhd. Any ideas what we can do????

Logs on the host server have nothing about the Guest system and/or corrupt VHD?

Not that i can see. There seems to have been a move back to a snapshot for whatever reason which you would think would be captured by the even log of the host but I cant find anything. Overall Im really confused as to how this has happened.

in terms of the recovery of data from the corrupt vhd the links provided by farazhkhan: have led me to sean based in Ireland who has nearly recovered a usable vhd file.

Hi,

So you are now running recovered .vhd file?

Hi,

Yes Sean at inetdesign dot com carried out the recovery and we retrieved all the data from the vhd. This was a second VHD drive that we kept all the data on.

Unfortunately the system drive containing the sharepoint and exchange data has not been recovered. i have 3 snapshots (I will never allow another production machine to have a snapshot!!!!!!!!!!!!!!!) from that system drive but cant connect them to a second vm. I dont want to try and attach them in any way to the now running SBS 2008.

Does anyone know if data can be recovered from snapshots?
