Subject: Help with intrepeting SATA log messages

Hello,

I was hoping that you could help me interpret these SATA errors from my
brand new Western Digital disk (at end). Also, this disk seems to refuse
smart commands:


# smartctl -s on -o on -S on /dev/sda
smartctl version 5.37 [i686-pc-linux-gnu] Copyright (C) 2002-6 Bruce
Allen
Home page is http://smartmontools.sourceforge.net/

=== START OF ENABLE/DISABLE COMMANDS SECTION ===
SMART Enabled.
Error SMART Status command failed
Please get assistance from http://smartmontools.sourceforge.net/
Values from ATA status return descriptor are:
 00     09 0c 00 00 00 00 00 00  00 00 00 00 00 50
 A mandatory SMART command failed: exiting. To continue, add one or more
 '-T permissive' options.


Whats up with that? :)

Thanks in advance,
  Rasmus
