</div>Yes, we should consider any drive to be failed if it gets any pending<br>

RMAing it instead of RMAing it as soon as you had 1 bad sector?</blockquote><div><br>I wonder if this new wonder tool davidz is working on Devicekit-disks will be able to give the user some more understandable warnings in this area. I e.g. have in the past 1½ years lost 3 drives, probably all problems of which I could have gotten early warnings and taken action instead of weeping over spilled data. <br>
