********** PLEASE HELP*********
Hi, Earlier today my laptop was working perfectly, I shut it down and put it on charge because when I was shutting it down I noticed my battery had only 40 mins or so remaining.
About 2hrs later I plugged in my external hard drive (that I use with this computer all the time) then turned it on and my finder wasn't recognising the external drive which can happen occasionally when i plug it in too early during start up!!! So i left it plugged in and selected restart just so it would detect it, but when it booted it back up all my desktop files/ folders had vanished? My display settings have all changed back to some default settings eg. background picture, my dock is now displaying things I never had there and has removed my final cut pro and all the other programs I had there??? All of my photos/ music etc have vanished, I've searched my Mac HD and its like everything has been erased?
I dont know how or why this happened, because nothing has happened to the machine, it was working 100% perfect...
So out of curiosity I ran the apple hardware test and its displaying error code 4SNS/1/40000000: TGOD.... I've browsed the web and Its coming up with different things for this error code from temperature problems to logic boards to some people having to get their Mac HD replaced!!!!

But my computer was working perfectly and I don't think its related to any of these issues.
Anyone have any ideas as to what it might be or how I can fix it??? Please reply if you can be of any help with this, Thanks, Tracy
