Troubleshooting lite-on-lite ltr-52246s

doesn’t read or write cd’s
haven’t seen much info on this subject anywhere? nero tools sees it and describes it(the cd-rw)-(and hardware manager lists it) perfectly yet there is no action other than opening and closing----won’t read or write.
am using xp operating system also
is also something i’ve used for last 9 months with no problem,

did search through your site but didn’t see anything relevant

thanks for any possible help or tips
