Sigma Posted March 7, 2009 Share Posted March 7, 2009 (edited) Hi, I've been using ImgBurn to burn 360 backups. I'm using an Optiarc AD-7200S burner with 1.09 firmware installed. I know there's a newer version than that, but I've been waiting on a Dee/Liggy modified version before updating. The discs I'm using are Verbatim MKM-003-000 (made in Singapore), rated at 8X. This is what happens when I try and burn at 8X: - 1. The speed seems to go in steps in a symmetrical pattern. 2. The second layer of the disc has a far higher number of PI errors and PI failures than the first.

LIGHTNING UK! Posted March 7, 2009 Share Posted March 7, 2009 What does the PIPO graph look like if you scan at 4x? Also, switch to 'Block' rather than 'Line' for 'Show PIE' and 'Show PIF'. Have you tried burning at the other 'Supported' write speeds? Link to comment Share on other sites More sharing options...
Sigma Posted March 7, 2009 Author Share Posted March 7, 2009 Thanks for the reply, Lightning. What does the PIPO graph look like if you scan at 4x? Here's a scan of the same disc at 4X: - Better results at that speed, but still a lot more errors on layer 2. Have you tried burning at the other 'Supported' write speeds? Yeah, I've tried 4X and 6X. Both had marginally worse error rates for the first layer, and about the same for the second. I've tried scanning a couple of my old MKM-001 burns in case it's an issue with the 003 discs because I've only just started using them in this last week, but they're the same. Looking good on layer 1, then the errors are way up on layer 2. Link to comment Share on other sites More sharing options...
Cynthia Posted March 7, 2009 Share Posted March 7, 2009 I have more or less the same writer as you - but the PATA version. I never burned that media id on that writer. I'll do some burns at the various speeds and post the results. 1. The speed seems to go in steps in a symmetrical pattern. I have the same pattern.

LIGHTNING UK! Posted March 7, 2009 Share Posted March 7, 2009 I don't think there's anything odd going on here.... everything looks perfectly normal to me with regards to higher error rates on the 2nd layer. Link to comment Share on other sites More sharing options...
Sigma Posted March 7, 2009 Author Share Posted March 7, 2009 Really? Well that's put my mind at rest anyway. Many thanks for the help. Link to comment Share on other sites More sharing options...
