I have a WD Blue 3.5" 2TB disk which does not seem to exhibit this behaviour. Maybe an older firmware version prior to the "green IT" move? I don't have Blue 2.5" (only SSDs) in laptops so I cannot counter-check. > Anyway, yea, I can see how this could possibly cause problems in the case of > *nix systems.

Get used to it - this will be the default of all "modern" items you will be able to purchase. In worst case, they come with a lower-level "know everything better than you" firmware that cannot be accessed or controlled from the OS. It doesn' matter if it's present in CPUs, mainboards, or hard disks; even cars, TVs, desk phones or heaters can be affected... :-( > I'm gonna try to see if I can disable this "feature" on this specific drive > and then see If I can maybe get it to complete the self test... which it did > not do the last time I tried.

"Bricked by firmware update" is nothing unusual in our "modern" "smart" time anymore. ;-) > However if your SSDs ever -do- start to spin, then you've got a real > problem on your hands. :-) If you put SSDs into an ATL and handle them like tape cartridges, well, floating, sliding and spinning becomes normal. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
