It is puzzling indeed, especially since I am running with TCQ enabled ever
since you introduced it and my disk is still alive an kicking. It being a
Deathstar, too.
On of my Deathstars actually broke (before TCQ came about though!) but
after upgrading the firmware on it and powercycling it fixed itself and has
been working just fine ever since.
Perhaps something worth trying on those broken disks, too?
