If not empty, likely you'll end up doing --update=force-no-bbl anyway. > # smartctl -l scterc,70,70 /dev/sdb ; echo $? > smartctl 6.5 2016-05-07 r4318 [x86_64-linux-4.8.13-100.fc23.x86_64] > (local build) > Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org > > SCT Commands not supported > > 0 It'd be hilarious if the timeout FUD on this list came with advice that didn't even do anything for most people, and nobody ever noticed... Unfortunately, it returns 4 here. And there are years old posts that explicitely check for it returning 4, so this shouldn't be new at all. Perhaps it's an intermittent error specific to your smartctl version? You can just set the timeouts unconditionally, if you really want them.
