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 ? What to look for ? # /usr/local/sbin/smartctl -a /dev/ada0 smartctl 5.42 2011-10-20 r3458 [FreeBSD 9.0-RELEASE i386] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Model Family: Western Digital Scorpio Blue Serial ATA Device Model: WDC WD1600BEVS-08RST2 Serial Number: WD-WXC308897633 LU WWN Device Id: 5 0014ee 2abfdb88c Firmware Version: 11.01G11 User Capacity: 160,041,885,696 bytes [160 GB] Sector Size: 512 bytes logical/physical Device is: In smartctl database [for details use: -P show] ATA Version is: 7 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Wed Feb 29 18:01:06 2012 CET SMART support is: Available - device has SMART capability.
