Greetings!
Drive problems are probably the most
well documented and sometimes the easiest to troubleshoot. Take a look at that entry and see if that helps your situation. If you are not comfortable opening or examining the unit yourself, I am sure there are folks around you that are. Where are you physically located?
As for the tuner, that is still a work in progress. There has been some movement in the queue recently - I think the last number I saw that was contacted was around 189. There is a
thread about that in the general forum...
