The worst possible situation...
Despite my vigilence doing backups, and trying to keep my PC secure, one of my VMs disk seems to be wiped out. Using the VHD tool from R1Soft (HyperV VHD Explorer), when I attach the VHD, it says no volumes found so it looks like something wiped out the VHD (which it still its original size).
It seems that something has sneaked through whatever security I have/had and has wreaked havoc.
Can I recover anything from this?
