Of course we could bail out of device_detect_all() when an error
occurs, I'm not sure though how useful this is. I mean when your
SATA drivers detect function returns an error because there is no
drive connected, why would you want to bail out of the detection of
other devices?
In an earlier version of this series I completely removed the -e
option. Maybe that would be better?
