Whenever attempting to copy a CD using Nero 6 a “write error” occurs, and the copying process stops. I have attempted to locally cache the source CD to the hard drive, then copy to the destination CD, but this does not work. The Ricoh Dual Layer DVD burner was returned to Ricoh (to check whether the drive was faulty) and returned as fixed but with no comment as to the cause of the problem. However, the problem remains. I also cannot write CDs using Windows Media Player, but am able to write CDs using Real Player 10.5. I can also write DVDs fine, so only copying to CDs causes problems. The computer has an 80 GB HDD, 512 MB RAM running Windows XP Home Edition SP2.
