In such circumstances, it is always best to leave the system alone until the verification and repair are complete. I would then suggest you run appropriate diagnostics to establish which drive is/was suspect, and possibly consider an early replacement. However, check the warranty on the suspect drive, just in case it is still covered. George.

I have my two hard drives mirrored (RAID 1). In case of a computer crash, after restarting the system I get a message says "The data in a volume is being verified and repaired". I'm just wandering, is it safe to use the system while the data is being verified and repaired?! Or the computer is better left alone until it finishes its thing? The repair takes good few minutes you know...
