The HDD of our server is broken and I almost lost all my data. The failing drive is the OS drive, not the data drive and ,yes, I set up raid5 on my server but I forgot to put MySQL data directory (/var/lib/mysql) into the raid array (still keeping it on the OS Drive).

Hiren rescue disk saves the day, however, some table is fubar and I can't do anything about it. You can notices that all tags are gone. Anyway, everything is up and online. On a bright side, it is a chance to upgrade from Stentz (FC4) to Hardy Heron.
