Hello,
I am seeing the following errors numerous times on one of our main file servers running Windows Server 2008 Standard x64.  

The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume .   NTFS Event 55
The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolumeShadowCopy8.

The errors only appear during the Backup Exec backup.  All other times the server responds fine.  I have heard varying opinions on running Checkdisk on hardware Raid 5.  What are my options?  There seems to be NTFS corruption as Backup Exec is having problems backing up certain files.  
Any advice would be greatly appreciated.

Thanks
Andy

I'm not at the site, so I will have to get back with you on the exact model Gateway.
Thanks for the assistance.

chkdsk is not raid aware, that being said run it in read only mode, make sure volume is not mounted or being used.  I however as a backup guy would strongly reccomend making sure you have a current backup in case of their is any corruption or any occurs.

Thanks for the advice.  I'm not going to chance the chkdsk.  Looks like a rebuild and restore is in order.
