Here's a WIP image..
- The last sector I was able to read before the ring is sector 297143, so error sectors start at sector 297144.
- Ring is from 297144 - 297699 (possibly the real start is 297150, but there's no way to tell, except maybe a microscope )
- Unknown data seems to starts at sector 297700.. so far I managed to read it up to sector 328468, so the size of this unknown data is 30768 sectors.
- A fake TOC file that matches these sector ranges: http://redump.org/disc/2210/
- Subchannels (partial subs from the unknown data range are included in the archive, but since it doesn't contain any protection data I guess the same data is generated during burning, so it should be useless)
How it should be burned (in RAW DAO 96, using a tool that can burn illegal TOCs):
- Sectors 0 - 13536 should be the same as the dump: http://redump.org/disc/2210/
- Sectors 13537 - 297143 should be audio (all zeroes)
- Sectors 297144 - 297699 should be data (burned as error sectors) or maybe it can be anything
- Sectors 297700 - 328468 should be data too I think (because there's a sync/header..)
It's pretty difficult to get an exact start and end position for the ring and the unknown data area because all drives give different results. But I guess it doesn't have to be 100% exact because the saturn drive propably won't be able to read the first and last sectors of it either.
What we need to find out:
- If the ring and the data after it are always the same amount of sectors and what the correct sizes are.
- If the location of the ring and the unknown data is always the same, or if it can be predicted in any way
- If this data is used for protection (if not, is there evidence of a wobble?)
