We had a rapid shut down by mistake when our SVN server in the office was unplugged and it caused data corruption.
update
The last commit to this SVN server was last Thursday. The power outage that caused data corruption happened on Friday. If I understand correctly this happened because the data was not finished writing to the disk which caused the corruption. How could it not be finished writing to the disk after over 24 hours? Is it possible that wasn't how it got corrupted?
