Why is it counting 150 sectors as part of write offset? Is it a bug?

Also my input for automatic offset correction:

There should be a limit on the maximum amount of non-zero samples that are corrected.
Looking at some of the large offsets that are dumped:
-9392 https://redump.info/disc/78870/
(next one is -4707)
+6722 https://redump.info/disc/1838/
(and several +5292)

It seems that maybe -10.000 to +10.000 samples seems like a logical range.

Here is my proposed method for automatic offset detection for Audio CD's:

Step 1: Determine the amount of non-zero data in the lead-out:
- If there are >10.000 samples of non-zero data in the lead-out, then this is a strange disc that violates Red Book standards. Offset correction is skipped and the disc is dumped with 0 offset?
- If there are ≤10.000 samples of non-zero data in the lead-out, then look if there's at least an equal amount of zero samples at the start of Track01. If this is the case, then proceed to use this as the custom offset correction (shift data to the left).
- If there are less zero samples at the start of Track01 than non-zero samples in the lead-out, then this is a strange disc that violates Red Book standards. Offset correction is skipped and the disc is dumped with 0 offset?
Step 2: This step should only be performed if no non-zero data was found in the lead-out. Determine the amount of non-zero data in the Track01 pregap, counting backwards from sector -1.
- If no non-zero data is found in the Track01 pregap, then no offset correction is required and the disc is dumped with 0 offset.
- If there are >10.000 samples of non-zero data in the pregap, then this is a strange disc that violates Red Book standards. Offset correction is skipped and the disc is dumped with 0 offset?
- If there are ≤10.000 samples of non-zero data in the pregap, then look if there's at least an equal amount of zero samples at the end of the last track. If this is the case, then proceed to use this as the custom offset correction (shift data to the right). If there are less zero samples at the end of the last track than non-zero samples in the Track01 pregap, then again this is a strange disc and 0 offset should be used?

The staff will discuss (and perhaps refine) this proposed solution and then we will inform you.

So likely something bad going on with the discs themselves even if they don't look visually bad.
Out of curiosity, try scanning the bad disc in a flatbed scanner. My near perfect copy of JSRF would not read correctly in either my Xbox 360 or my Kreon drive, and I couldn't make sense of it. When I scanned the disc on the flatbed, though, there were tons of tiny little black spots that I couldn't easily see with the naked eye.

I think maybe one of the Xbox disc manufacturers had an issue with some batches of discs, and they're oxidizing or otherwise rotting away. I've seen reports of other perfectly good looking JSRF discs having the same problem, and I'm sure there are others besides the JSRF discs.

I'm pretty sure my JSRF disc did not have this problem when I purchased it new years ago. I vaguely remember having a modded Xbox extract the disc shortly after purchase, so it was readable at that time, and it's been in the case ever since. I didn't try dumping it proper until I finally got a Kreon drive this year, though I noticed last year that my 360 wouldn't play the disc.

As it is written in the comment of https://redump.info/disc/77974/ , these discs start AMSF 00:00:00, not 00:02:00. Due to this problem, there is not the sync in the last 150 data sectors. EccEdc judges it as error.

I translate the src I already coded to English. Thanks to Intothisworld, perhaps it's almost coded except -10.000 to +10.000 samples you say.
I hope to test the latest version of the https://github.com/saramibreak/DiscImag … /issues/95 to more people.

Code: Select all

1. Check the non-zero byte position from last - 75 to last + 75.
2. Check the non-zero byte position from LBA 0 - 75 to LBA 0 + 75.
3-1. If the difference of the last non-zero byte position and 1st non-zero byte position are bigger than 0 sample and smaller than 588 samples...
3-1-1. If the last non-zero byte position is equal to the 1st non-zero byte position, Set the custom offset.
3-1-2. If the last non-zero byte position is bigger than the 1st non-zero byte position, It can't set the custom offset.
3-1-3. If the last non-zero byte position is smaller than the 1st non-zero byte position.
3-1-3-1. If the 1st non-zero byte position is smaller than the combined offset, Set the custom offset.
3-1-3-2. If not 3-1-3-1, it's no need to fix the combined offset.
3-2. If the difference of the last non-zero byte position and 1st non-zero byte position are bigger than 588 samples... (last < 1st)
3-2-1. If the last non-zero byte exists in the last sector or lead-out and the 1st non-zero byte exists in the LBA 0 or backward.
3-2-1-1. If the last non-zero byte position exists in the last sector and its position is smaller than the combined offset, it's no need to fix the combined offset.
3-2-1-2. If not 3-2-1-1, set the custom offset.

@sarami: I wanted to know how you did dumped that disc: https://redump.info/disc/45814/

Did you just used the /sf command for Bitpool?

In the past Bitpool discs were 'fixed' with custom tool (replacing with 0x55). But recently it's was considered imperfect and all Bitpool discs have to be redumped without any kind of 'fixes'.

Here is my log: https://drive.google.com/file/d/1wj281R … sp=sharing

Something weird is going on on my side. In your logs it seems the protected sectors are handled correctly but on my side it tries to reread some of the sectors despite being already detected as protected.

Here the console output too:
