Nero V6.0 How to burn UDF CDs with sparing partition



Hi. I am writing software to play compressed audio on UDF CDs. I am facing a problem with verifying my software with CDs containing UDF filesystem with sparing table. I need to test the filesystem parser with discs containing sparing table.

I haven’t found any test discs on the OSTA site, nor am I able to create such discs. I have Nero version 6.0 OEM version which came alongwith my Sony DVD writer drive. Although I select Sparing Partition, UDF 1.50 in the burning menu tab, the selection is reset automatically to Physical partition. To simulate bad sectors I have tried scratching the disc and putting dots and dashes with permanent marker pen. But no luck until now. Can someone help me ?
