Thanks for your help Alex!

Unfortunately, it is always difficult to update the kernel in an embedded system. So I'll try to use the patch.

Hi Alex,

thanks for your prompt reply!

with '-d sat' I have less success:

/ # smartctl /dev/sda -d sat -H
smartctl 6.1 2013-03-16 r3800 [mips-linux-] (local build)

It seems that this kernel is too old and not implementing SAT support. I found patch for 2.6.12 [1], may be it will help you. Or just use recent kernel, if possible.
