I have a server running home server 2011, and have been receiving an event log entree that seems to show up every morning just after midnight every night. The entree states The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume. I have run chkdsk on both the C and D drives, and no issues have been found. I have also run a sfc \scannow, and no issues were found. windows updates are current, and I think this may be a task running at this time to cause this, but can not seem to find anything. Any assistance with this would be great!
