VHDX file corrupted

Hi guys,Really need your help on this one.

I have a customer that uses Hyper-V on Windows Server 2012 RTM.

The earlier IT guy (who was fired today) have been running the whole setup on dynamic disks.

One of the disks have 3,5 TB of data, and is therefore a VHDX file.
Today because of the heat the RAID controller reset, and that sadly corrupted the VHDX file.
Almost all of the VM’s are dead, but this VHDX file holds ALL of the company data - such as dokuments, pictures, contracts, profiles, homedirs, and so on (you probably get the picture).
To top it all, the (now fired) IT guy didn’t really check on the backup jobs - so no backup at all.

This company really needs help. I tried Bing’ing and Googling everything but no help as it is a VHDX and not a VHD file.

Whenever I try to start the machine, all I get is "Attachment ‘D:VHDsFILESERVER1.vhdx’ failed to open because of error: ‘The file or directory is corrupted and unreadable.’."

I tried attaching it in disk manager with no luck (it will not open). I read that extending the size with VHDResize could uncorrupt the drive could help (but sadly it does not support VHDX format).

I really need your help here. Please join in with every crazy idea available.. These guys really need help.

The guy that comes up with a solution will not only recieve the credit, but I personally promise you an ice cold beer if you ever get to Denmark..

Or if you live in a country that I will ever visit, I will buy you one in your town.
