hard disk behavior
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 ? Any other tools, except SMART below, to try ?

Re: hard disk behavior
Hi! 2012/2/29, jb jb.1234a...@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. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Yours is quite high. You may be able to use sysutils/ataidle to disable the parking like so: ataidle -P 0 /dev/ada0 Not entirely sure if this works on the ada driver, so if not you might want to ask on freebsd-stable@ or boot up in a Live CD of Linux and use the tools there. -- Adam Vande More ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
