Many CD-Rs have Errors in their Last 2 Sectors due to how the discs were "mastered". These dumps are usually not bad, but require extra steps to ensure QC when adding to redump.

Steps

  • Dump your disc to confirm it is getting c2 errors only at the end (last 2 sectors).
  • Run the command "redumper [dump name] --force-split" (this will replace the error sectors with 0x55 and create a .bin file).
  • Dump a second time to ensure your .bin has matching hashes.
  • Now the .bin info is ready to submit to Redump.
  • Copy + paste the link to this guide in your submission the Moderator adding your disc will have context.
  • Also include two sets of MPF/redumper logs showing matching results.

Notes

  • For multi-session CD-Rs, errors may appear at the end of EACH session.
  • redumper may erroneously (mis-)correct CD-R errors when refining the dump. A correcting of C2 errors at the last 2 sectors of a CD-R should be considered a bad correction.
