Normally fsck is run during boot, before filesystems are mounted 
read/write.  You should only be dropped to the emergency shell if errors 
are found in filesystem, in which case you will be asked if and how 
those errors should be fixed.

Advanced filesystems like btrfs and ZFS have checksums and other 
reliability measures that will help the filesystem driver automatically 
repair errors.
