my ricoh mp7240A burner wont burn my cds anymore. Well ihad this problem for a while now maybe 3months but i thought i had crappy cd-rs. It reads cds just fine but sometimes when i read burnt cd-r/cd-rw, it wont read it. But original cd e.g. music , games, software. it reads fine. Is there a life expencancy with cd burners? It wont burn either, with nero or mp9. It says cant "disc speed error'. And the funny thing is, both nero and mp9 just spits out the cd and the cd isnt a coaster even. It still works. So im saying is it dead or do i need to buy like a cd lens cleaner or something? if it needs cleaning, ill go buy some later today. Help? or else i have quite a heavy paper weight or door stopper.
