I have some problems burning content in Redump format with pregap of 01:74 at second track. ImgBurn seems to autocorrect this, the verification after burning also fails. In this example I am trying to burn Astal (USA) for Sega Saturn. But also had the same problem for Shining Force CD (USA).
Here is the log at and after verification:
...
W 22:51:16 Session 1, Track 1 is smaller on the disc than it is in the image file.
W 22:51:16 Disc's Track Sectors: 261676 (TOC Sectors: 261826)
W 22:51:16 Image File's Track Sectors: 261677 (TOC Sectors: 261826)
...
W 22:53:40 Miscompare at LBA: 261676, Offset: 2064
W 22:53:40 Device: 0x00
W 22:53:40 Image File: 0xE7
W 22:53:40 Total Errors in Sector: 52
W 22:53:40 Note: The drive probably corrected the EDC Area because it's wrong in the image file.
...If I burn the same content with Alcohol 120% and verify burned media with ImgBurn afterwards, there are even more errors count. I also tried burning with the old CDRWIN v4.0H but after the burning process the disc was not recognizable at all by any of my PC drives. All drives had issues reading the disc with heavy access to the disc several minutes blocking the eject mechanism. I think CDRWIN actually burned the content 1:1 as described in the .cue file but was afterwards incompatible with PC cdrom drives?
I will come back after dumping some media.
