Did your OS unexpectedly shutdown? Power outage? Some external event that would result in your filesystem corrupting files? Or did the problem just occur somewhat randomly?

EXT4 is a journaling filesystem and is usually configured to perform an fsck every 50 or so boots. Usually, the only time I see corrupted files is when I forget to set an fsck interval or when a hard drive begins to fail.
