I've been noticing that lately my Pluto system's HDD has been grinding a lot. And by a lot I mean all day, non stop. Does anyone have any idea why this is? What I could do to stop it? What I'd need to check to figure out what's going on? It's a hybrid system with the installation using default partitioning and file systems on a 60 gb drive. There's also a 180 gb NTFS drive in that machine, and I'm not sure which one is grinding (though I'm assuming it's the 60, as that's where Pluto is actually installed).
