Event 55 -The file system structure on disk is corrupt and unusable / Hyper-V

Hi,

We have a Hyper-V virtual server running server 2008. Recently we got an error in event logs. We did not see an impact on the server related to this issue yet. There are many errors and I know there is a hotfix for this issue for Server 2003 but I couldn't find any hotfixes for Windows Server 2008. What would be the solution for this issue? Also this is a virtual server, is it normal to get this kind of error on a virtual server?
Any help would be appreciated.

Thanks!
