No disc read in Tdk880n/Nec 2500a

The PC recognizes the drive,as does InfoTool,but when I insert a disc,CD or DVD,blank or full,I get no recognition,please help…Thanks In Advance

I purchased a 2510a from Newegg in July, and last week, after I used DVDinfoPro to erase a DVD+RW, the drive stopped reading/writing to DVDs… It still read CD/CDRs fine, but it would not read/write DVD+R/RW, -R nor would it read DVD Videos. Guess the laser went bad. Anyway, RMA’d it to Newegg, and they are sending me a 3520a.
