I have this disc https://redump.info/disc/5037/

I dump it with CloneCD, PowerISO, ISOBuster and Alcohol 120% (using the CloneCD format and the CUE/BIN) and got the matching SHA-1!

However, when I dump it with DIC I got the same file size but diferent SHA-1
I use this command "dic cd e syphon 8 /c2" (also without /c2)

What am I doing wrong? What command should I use to dump PS1 non protected games?
Thank you all

.img is a different format. Redump with IsoBuster to bin/iso option.

Hi escarlata!
Please redump in a new directory with DIC and post the log files and complete psxt001z and edccchk printouts.
This line is quite strange:
     EDC in Form 2 sectors: YES
This disc has no EDC and also the exe date is missing in your psxt001z printout.
Do you have a plextor drive? If so, which model?

I don't have a Plextor drive, however it is capable of doing scrambled data, and this is a standard PS1 disc... do I still need it? Besides, I got a matching sha1 with all other tools!
Do you still want the logs?

Yes, let's start with the logs. Post a link to them here (no img or scm files)

Thanks!

I redumped with the "/nl" command and here you have some errors, I also uploaded the logs here:

It seems your drive doesn't support reading lead-out.

This drive can read a data sector at scrambled mode [OpCode: 0xbe, C2flag: 1, Su

This is bug. scrambled dumping isn't supported too. Please use the recommended drive.

I understand that my drive doesn't support reading lead-out, but how come I got a matching hash with all the other programs? Alcohol, PowerISO, Isobuster, CloneCD...

Because these programs dump the data sector as data sector (0xbe mode), but dic dumps the data sector as audio sector (0xd8 mode), then audio sector is descrambled to data sector.

Thanks for the explanation sarami!
I guess I'd need to purchase a Plextor drive...
