I hate to say it, but have you tried the Sony VY06 firmware. Consensus is that it burns -R better than Liteon firmware. You can get it from my site (follow the link in my signature). Don’t forget to enable cross flashing with OmniPatcher if your drive hardware is not an 832S.
BTW: To save and attach a KProbe scan:
After the scan is complete, click the small diskette button on the toolbar and at the save as dialog select a file type of .PNG. Attach the saved file to your post by using the “Manage Attachments” button in the “postreply”, “Go Advanced” or “Quotepost” mode.
