I recently purchased the Aura box after reading reviews.
Humax support seem quite useless as having a few issues, it really does seem to have a huge number of teething problems.
My main one is that the hard drive is constantly on, my room is very quiet and so even when everything turned off (standby) the HDD is spinning and I can hear this. This happens indefinitely and not just for a few minutes after entering standby.
Is this the expected behaviour or should it be turning off? Humax blamed it on the smart/server features of the box but can't imagine it would be programmed to be on 24/7 for the whole life of the box.
