I got HD installed yesterday. My SkyHD hard drive is making an awfull noise when recording, watching and pausing HD programmes. It's a very loud sort of ticking noise. If I turn up the volume on the TV it can't be heard, but if I watch at night when the wife and daughter are in bed I need to have the volume low and the noise is very annoying. I have spoke to Sky and they say they have never heard of the problem before and are sending out an engineer. Do you think I should insist on a new box? Would the engineer do this ? Has this problem been heard of before on these forums ?
