I have a Sony DRU500A burner in my XP-based system, which has worked for over a year. Starting last week, any application capable of burning a CD or DVD issues the message: "No compatible Recordable or Rewritable devices could be found on your system". The drive can read CDs and DVDs just fine. I've swapped out the drive, but get the same message on the alternate burner. I've deleted the driver in Device Manager and rebooted. XP never acknowledged a new device. It just came back up in the same state as before. Anyone have any advice?
