SMART only catches hard drive defects. Some other things that (I think more frequently) can lead to file system corruption, even on a system that seems to be running just fine, are: - Small RAM errors - Overheating components - Overclocked components - Software bugs (kernel/VFS/filesystem driver) - Hardware bugs SMART won't help you there. Only fsck will. Currently, I believe there is a check during boot to see if the system is running on battery power, and if so, delay the fsck for 10 more mounts or until the system is booted with mains power again. Other suggestions have been to have a (kernel?) thread/process in the background constantly checking your filesystem when the system is otherwise idle. The same type of process for background defragging has also been suggested. However, I am not aware of anyone ever implementing a workable prototype of such a system for Linux.
