.. ERROR CODE 4450 HELP PLEASE!.. I copied my cd/dvd diagnostics here

Question

Hi, I used to always be able to burn CDs on my computer with iTunes fine and now I keep getting error code 4450 right after the 1st song begins to burn. My computer is not even one year old yet! I tried reading other topics like this one but I could not figure out how to fix the problem myself. The questions were responded with asking to run the cd/dvd diagnostics on iTunes so I did and here they are... PLEASE HELP ASAP! THANK YOU!!!

If you have multiple drives on the same IDE or SCSI bus, these drives may interfere with each other.
Some computers need an update to the ATA or IDE bus driver, or Intel chipset. If iTunes has problems recognizing CDs or hanging or crashing while importing or burning CDs, check the support site for the manufacturer of your computer or motherboard.
