So, I discussed this with upstream: <mezcalero> if we encounter an USB disk we try to find out if it speaks SAT <mezcalero> we do that the hard way: <mezcalero> by sending it some commands <mezcalero> some shitty bridges tend to hang themselves up due to that <mezcalero> or reset themselves <mezcalero> there is not much we can do about that <mezcalero> we had similar reports regarding usb sticks <pitti> reportedly the drives pretty much stop working entirely, though <mezcalero> because an usb stick does not look any different from a HDD drive to libatasmart <mezcalero> so if you look into the udev rules of dk-disks <mezcalero> there is now a check based on the disk *size* which disables ata smart <mezcalero> this catches most of the broken usb sticks <mezcalero> however, of coruse bridges for HDDs are not covered <mezcalero> and we need to blacklist them all seperetely <pitti> mezcalero: interestingly, though, the calls eventually succeed and report that the drive is smart capabl <mezcalero> pitti: hmm, so yes, i am suggesting you add blacklist rules for this
