The datacenter reports that the disk is only warm to the touch.
Is there a possibility that the SATA disk is returning different
raw values?  I had to specify "-d ata" to get smartctl to work.
Without this option, I get

[jhg@helios ~]$ sudo smartctl -a /dev/sda
smartctl version 5.33 [x86_64-redhat-linux-gnu] Copyright (C) 2002-4 Bruce Allen
Home page is

Device: ATA      WDC WD1600JS-55M Version: 10.0

SATA disks accessed via libata are not currently supported by
smartmontools. When libata is given an ATA pass-thru ioctl() then an
additional '-d libata' device type will be added to smartmontools.

Betreff: [smartmontools-support] WDC WD1600JS unknown attribute 190 question

I did a google search and found some postings that indicate attributes 
190 and
194 both indicate the current temperature in degrees celsius.  Is this 
also true
for WD SATA drives?  I recently leased a dedicated server at and
get the following when running smartctl.  Everything looks normal except
190 and 194.  If they're really temperature, then there's a serious
problem with cooling.  I want to be sure this is true before I submit a
support request to them.


Yes, Attribute 190 in WD drives seems to be temperature with a 
threshold at 55 degrees, Bruce made some comments about this recently.

And yes, you have a problem. See the "FAILING_NOW" message, which
means that WD considers this as "no good".
