I have three WD Sata disks (Western Digital Caviar Green (Adv. Format) family) all with the same model no: WDC WD20EARS-00MVWB0, but different Revision No. All drives have smart support and two of the disks are smart enabled. When enebling the third I get the following: +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ llist@LeosLinux:~$ sudo smartctl --smart=on --saveauto=on -a /dev/sdd [sudo] password for llist: smartctl 5.40 2010-07-12 r3124 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Model Family: Western Digital Caviar Green (Adv.

The controller driver or firmware probably fakes a SMART data block and reports temperature only. Is this some RAID capable controller in non-RAID mode ? If possible please try smartctl with this drive connected to a different controller. Thanks, Christian |
