Hi! 2012/2/29, jb <jb.1234abcd@gmail.com>: > Hi, > I very often hear this metallic (mechanical) clicking from my hard disk when > it is active. I experience this behavior under FreeBSD only (not other OSs). > Is there any way to figure out what it means ? Some time ago I had a similar problem with an external WD Scorpio Blue disk. As my point of view, it tends to park its heads too often, even under heavy load, so this results in a clicking. As far as I remember, you can check Load_Cycle_Count from SMART output. Take some measurements during minute or two. Rapid growth of this parameter indicates a problem.
