I am running VMs on Hyper V 2008. Yesterday I noticed that one of my VMs has a volume/disk that may be corrupt. I tried to run a chkdsk on the C: drive and it came back clean. When I attempt to run a chkdsk on the D: drive it comes back with the following error: "The type of the file system is RAW. Chkdsk is not available for RAW drives." When I read this I take it as my OS thinking that the drive has yet to be formatted. At one point it was and it currently has data on it however the data doesn't appear to be stable anymore because of the underlying disk/drive issues.
With this being a VM and not an actual physical disk. I'm trying to find ways to restore the volume without losing the data, if such a way exists.
