I know this is an old thread but I feel my two cents' worth might help others in the same situation.
Yesterday my HDR-1000S suddenly decided to 'lose' all my recordings. I turned to this forum looking for possible answers. The settings menu on the Humax told me to attach an HDD, so I assumed that I had a fault on the HDD or controller etc.
But then a little light bulb came on in my head; yesterday, I rearranged the HDMI cables on my TV and part of that involved swapping a newish hi-speed HDMI cable for an old one (not sure what spec) that was more suitable as regards length. That, believe it or not, turned out to be the problem. When I reinstated the previous cable (the hi-speed one), all the recordings came back and, once again, when I put the old cable back in, they all disappeared again.
Completely clueless as to why... anybody? The old HDMI cable appeared to work ok otherwise, the only difference being the disappearance of my recordings.
