I suppose this hard drive should be blacklisted (NCQ is disabled because
of this errors anyway).

I'm a bit afraid. Nothing happened so far (no data loss and I've Ubuntu installed on this laptop for two 
weeks) but my first installation (Arch Linux) ended up with a filesystem corruption, possibly 
because of my attempts to get suspend to ram working.
