I've recently purchased hdr-1100s & contacted humax with my question but no response as yet.
When my box is in standby (red light on front), the box is initially silent. About every 20 minutes I hear the hard disk start up. After 2 or 3 mins it shuts down again and is silent. This cycle continues. No recordings are scheduled so is there a logical explanation why the disk needs to.spin up every 20 mins? I think the fan comes on too.
It's in a bedroom so at night the noise is disturbing. I've tried the 2 different standby modes but same result.
My solution currently is to connect it to a timer so it stays shut down at night.
Thanks
