[Edited by Moderator]
Click Ignore, choose Utilities from the Finder's Go menu, open the Disk Utility, and use the First Aid or Repair Disk function depending on its version. If this doesn't work, use a non-Apple repair tool or a data recovery program.

FYI, while it won't help you right now, you should make sure to have a good backup of any external media which contains important & unique data. Plus as you are now discovering......RAID itself is not a backup.
