I'm changing the code for dumping the multi-session disc https://github.com/saramibreak/DiscImag … issues/208 . Please wait a few days.

EDIT
Updated test version. https://github.com/saramibreak/DiscImag … r_test.zip

@sarami

Thanks for this, unfortunately it doesn't solve the issue I'm having. In order to correctly calculate the session lengths (see comments for https://redump.info/disc/102164/) we need _disc.txt to contain the following as it did previously:

- Lead-out length of 1st session
- Lead-in length of 2nd session
- Pregap length of 1st track of 2nd session

No version after 20220909 (including the test version above) includes this information. As such we are unable to process some multi-session dumps made with recent DIC builds

"Lead-out length of 1st session" is 6750.
"Lead-in length of 2nd session" is 4500.
"Pregap length of 1st track of 2nd session" is 150.
They are always same.

I've recently encountered an issue where DiscImageCreator is failing to report DVD read errors on multiple discs, while Isobuster and redumper both report read errors. I believe these read errors are resulting from hardware failures from my internal DVD drive, and not disc errors (they are flawless discs and read without errors on other drives). I have experienced these symptoms with builds 20220707, 20230303, and 20230413. This results in 2048-byte blocks containing NULL bytes instead of the correct bytes.

In DIC code, I see that it doesn't directly check ScsiStatus, but rather:
Is it possible that because DIC doesn't directly check ScsiStatus, that it is missing some bad reads?

Attached are logs for the GOOD and BAD dump from DiscImageCreator for a specific disc with the failing drive (both report no errors in the log).

Try this test version in this thread(https://github.com/saramibreak/DiscImag … 1551409465)
And use /ps aa, please.

Trying to dump an audio CD on Mac, can someone (who's done it before) tell me where I'm going wrong?

here's my command: audio disk6 clubsaturnusa 72

The example command: audio <DriveLetter> <Filename> <DriveSpeed(0-72)> <StartLBA> <EndLBA+1>

Dunno how to get these: <StartLBA> <EndLBA+1>
are they required?

So it turns out that dic and redumper CLI can only be run through certain directories on macOS. (It won't work out of Downloads folder or the Desktop for instance).

What we got to work for redumper is /Users/[username]/bin

https://drive.google.com/file/d/1cikxNb … 4O5P6/view - the log is full of "Subchannel & TOC doesn't sync." messages, but no "Sub Indexes" tracks/cue created? Why?

I dumped Tengai Makyou: Ziria(https://redump.info/disc/37134/) and "Sub Indexes" are dumped. I'm not sure why Ys Book I & II (USA) are not dumped.

Can you add more debug info logging to understand the problem?
