mikec Posted May 1, 2007 Share Posted May 1, 2007 (edited) If anyone can help with this, I would appreciate it. I have burned a lot of discs over the years, and never had many issue; always use good burners and media (update firmware, Verbatim disc, etc.) I am trying to make a working backup of my navigation dvd for my car. I learned long ago with kids that you need to make backups, as they love pressing buttons and handling discs. Here is the info of the original disc ISO: Current Profile: DVD-ROM Disc Information: Status: Complete Erasable: No Sessions: 1 Sectors: 3,603,491 Size: 7,379,949,568 bytes Time: 800:48:41 (MM:SS:FF) TOC Information: Session 1... -> Track 01 (Mode 1, LBA: 0 - 3603490) -> LeadOut (LBA: 3603491) Physical Format Information (Last Recorded): Book Type: DVD-ROM Part Version: 1 Disc Size: 120mm Maximum Read Rate: 10.08Mbps Number of Layers: 2 Track Path: Parallel Track Path (PTP) Linear Density: 0.293 um/bit Track Density: 0.74 um/track First Physical Sector of Data Area: 196,608 Last Physical Sector of Data Area: 2,082,239 Last Physical Sector in Layer 0: 0 Layer Information: Layer 0 Sectors: 1,885,632 (52.33%) Layer 1 Sectors: 1,717,859 (47.67%) ---- I made an ISO of this disc, and burned a copy to a Verbatime DVD+R DL disc, with booktype set to DVD-ROM, and write speed 1x. Here is the info on the copy: Current Profile: DVD+R DL Disc Information: Status: Complete Erasable: No Sessions: 1 Sectors: 3,603,504 Size: 7,379,976,192 bytes Time: 800:48:54 (MM:SS:FF) TOC Information: Session 1... -> Track 01 (Mode 1, LBA: 0 - 3603503) -> LeadOut (LBA: 3603504) Physical Format Information (ADIP): Disc ID: MKM-001-00 Book Type: DVD+R DL Part Version: 1 Disc Size: 120mm Maximum Read Rate: Not Specified Number of Layers: 2 Track Path: Opposite Track Path (OTP) Linear Density: 0.293 um/bit Track Density: 0.74 um/track First Physical Sector of Data Area: 196,608 Last Physical Sector of Data Area: 16,580,607 Last Physical Sector in Layer 0: 2,283,519 Physical Format Information (Last Recorded): Disc ID: MKM-001-00 Book Type: DVD-ROM Part Version: 1 Disc Size: 120mm Maximum Read Rate: Not Specified Number of Layers: 2 Track Path: Opposite Track Path (OTP) Linear Density: 0.293 um/bit Track Density: 0.74 um/track First Physical Sector of Data Area: 196,608 Last Physical Sector of Data Area: 16,412,847 Last Physical Sector in Layer 0: 2,082,239 Layer Information: Layer 0 Sectors: 1,885,632 (52.33%) Layer 1 Sectors: 1,717,872 (47.67%) --- The copy burns fine. But when I put it in the navigation drive, the disc is not recognized. "DVD not readable/wrong type"; some type of message like that. I have made about 3 copies, all with the same results. So here's where I am: - I think the PTP vs. OTP has something to do with it, but I'm not sure. - This disc info for the original disc and copy are not the same; shouldn't they be? I suspect it might be related to PTP vs. OTP, but again, not sure. - Any ideas on how to deal with this? Do I need another app? (ex. PgcEdit) Any pointers would be appreciated.

dontasciime Posted May 1, 2007 Share Posted May 1, 2007 This has popped up quite a bit and I do not think anyone has a fix for this. Off to search google again. [edit] http://forum.imgburn.com/index.php?showtopic=2628 Link to comment Share on other sites More sharing options...
LIGHTNING UK! Posted May 1, 2007 Share Posted May 1, 2007 Give up trying. If it doesn't work now, it's not going to. Link to comment Share on other sites More sharing options...

[edit] http://forum.imgburn.com/index.php?showtopic=2628 Yes, I had poked around, but was looking for a definitive answer. It sounds like it is impossible to make a backup.
