Does this unit support the S.M.A.R.T. standard via the USB 3.0 interface? If not via USB, at least via eSATA? (SMART is used to monitor temperature and read/write errors).
Under Linux, the disks appear in the ICY BOX as normal devices (e.g. /dev/sdb for the first disk, etc.). SMART also works with the usual tools (e.g. entering "smartctl -i /dev/sdb" confirms that SMART is supported and active).
