I have updated the information for that Error:

5) Error: 'TEST UNIT READY' command failed on device 1:1:0. Device contains no disc or is not ready. (04h 00h 02h 02h 3Ah 00h

or it might appear as:

Error: 'Start DAO Recording' command failed on device 3:0:0 Disc type is not supported.

ANALYSIS: This occurs with any of the DVD-/+R drives. This includes the Plextor PX-W708, PX-W712 Px-W716 DVD Recorder Models. Some users have seen this when installing some Printer software drivers.

SOLUTION: Remove Roxio EZ CD Creator 6 and Nero 6 or any other Burning program from starting at boot. Most of the time you can go into the programs settings and turn off the option to start the program at Windows Startup. These programs are known to cause this error.
