This error is due to something on your computer slowing the Data transfer down to the point that it is not making it to the drive fast enough to write.
This can be caused by Spyware, Viruses, bad Motherboard drivers. It is somewhere between your Hard drive and CD-Rom drive. This uses the Computers Motherboard drivers to transfer data.
