I know that this topic is a bit old, but I have a very similar question.

Every two weeks we perform server/database maintenance; altering indexes, Windows updates and a server reboot. My issue periodically appears between maintenance weeks with a System error Event ID 55 in the event viewer: "The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume XDATA."

This volume is on our SAN and I've determined that I need to perform a CHKDSK since the volume is marked as dirty.

I understand the differences between CHKDSK /F & CHKDSK /R. My question is since I'm not performing a CHKDSK /R should I be worried about database files on this volume if I perform a CHKDSK /F?
