Find your broken partition then run
on that partition from the debug shell or a Fedora 16 (non beta) live cd.
You probably lost some files.
Check the smart values for that drive with
smartctl -a /dev/sdX
When it's up and running again you should run a self test on that drive
smartctl -t long /dev/sdX
This will take a couple of hours depending on the size of the drive since it's trying to read all sectors on that drive.
