Your hard drive will crash soon. Backup your data immediately!
Sorry for the dramatics, but all hard drives fail eventually - It's just a matter of timing. Make a backup of your files to be safe. You want to end up with two copies of everything. (Copying them to an external drive and then deleting them from the original drive is not a backup as you still only have one copy.)
