Cd/DVD burner not working

[qanda]This thread is about the DELL 160GB Internal Serial ATA NCQ Hard Drive for Dimension 3100/E310/5150/E510/5150c/9150/9200 and Select XPS. Click here to see full specs[/qanda]Hi, new to here. My computer cd/dvd drive would not open unless I manually opened it, so ordered a replacement, hooked it up just like the old one. Now when I go to burn a cd, it goes through all the motions, the software (real player this time), says it is burning, but when it is finished, the cd is blank still. What is going on?
