DiscImageCreator

[sarami]

Your startopia and Battlefield 1942 have C2 errors except 312 and 288 bits. You or other person needs to get mint-conditioin disc, I think.

I've got a disc with three audio tracks followed by one data track. The dump completes without /ms, but the last track is misaligned. Running DiscImageCreator with /ms seems to work fine, but Read error. padding [2352byte] starts to appear around the area where the data track begins.

some changed about /ms http://www.mediafire.com/file/eq80y20l9 … st.7z/file

but Read error. padding [2352byte] starts to appear around the area where the data track begins.

My plextor (755sa, 4824a) can read only 6 sectors about lead-in of 2nd session.
191391 is the last sector of 1st session. 191392 - 195891 are leadin of 2nd session. 195892 is the 1st sector of 2nd session.

Perhaps admin or moderator will judge it properly.

I haven't understood if the sector is damaged/wrongsized or just has some additional sync bytes before the actual sync.

[sarami]

I think "just has some additional sync bytes before the actual sync." But the dumping of another disc is needed for verification.

[F1ReB4LL]

If you can cut the unneeded bytes and descramble everything with no errors, the errors count should be 0.

[F1ReB4LL]

DIC dump to the left, old bin-cue dump to the right. And I really don't think these 2 bytes should be zeroed.

How about cdtoimg?

The disc has been returned to its owner already (who doesn't have any Plextor), but it constantly gives the proper bytes (like on the right) with all the 0xBE reading tools (IsoBuster, CloneCD, etc.).

[celebi]

If you can cut the unneeded bytes and descramble everything with no errors, the errors count should be 0.

Was that related to the disc in question I dumped? If so, can you lead me to the steps how I can strip the unneeded bytes and manually descramble the file?

[F1ReB4LL]

You need to cut all the bytes before "00 FF FF FF..." with the remove.exe, then descramble the rest of the image with one of the software descramblers, then check the descrambled image for errors. The last sector in the scrambled image will be incomplete, so the last sector of the descrambled image will be missing, you will need to read it separately and join to the end of the image.

/viewtopic.php?t=14816 … firepower/ -- why does track 3 has 00:02:00 pregap? The subchannels start at AMSF 10:02:00, while the pregap goes from 10:00:00 to 10:01:74. Do you generate the cue instead of properly reading/converting the subchannels?
