We have a Windows 2008 R2 64 bit server. We have a C volume (OS) and D volume (data). D volume is RAID5 with 4 physical disks.
Everyday at 2:26 am, 10:26 am, and 6:26 pm, it reports event ID 55 with source NTFS with the following description for the D volume:
The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility....
I run check disk but it does not find any error. I have checked the hardware logs but no issue is reported.
There is no scheduled task that runs at 8-hour interval that I know of and I cannot find anything else that does.
Anyone has any idea? Thanks.
