Sometimes my hard drive grinds away like a coffee grinder. Nothing bad happens on the screen and everything runs just fine, but I wonder why it occasionally goes 'crazy' like that. Most of the time the hard drive runs nice and quiet. Its a 40 gig Samsung SV4084H. I know what swapping is and I can't think why it would be swaping. I've got 384 megs of memory and gave Red Hat 7.2 128 megs of swap. Perhaps its something I have not done. Is there some method to optimize memory or hard drive space?
