I hear of data corruption from clients frequently. It's a combination of write delay, network delays, and a different program putting a lock on the file. Usually we find out there was a change. New hardware or new software in most cases. I'm glad others don't have corruptions. On Windows 7, the policy settings tab isn't visible until you're in administrative privilege mode. Must be a driver setting forcing it to always on. It's good to know some systems may prevent that.
