im not sure if this is the right place to post or not, if not feel free to move it my cd-rw drive is a sony crx-230E and dvd drive is a HL-DT-ST DVD+RW GRA-4120B my problem is for some reason the cdrw drive will read cd's and software discs fine, but will NOT burn anything when using musicmatch, nero, or even windows to burn files, music or anything to a cd. My dvd burner is what i use to burn music and what not with, but even my dvd writer will only work with musicmatch, nero, and a couple other programs i use to burn dvd's, but the problem is that any time i use the windows cd writer it comes up with an error saying the wizard could not complete the disc burn or something like that, it doesnt even try to burn it just pops right up as soon as i click next or burn, it does that for both drives and like i said my sony cd-rw always comes up with an underrun error on musicmatch, and always messes up my cds. My computer is about a year old and it just started doing this one day... what could be the problem?
