Guess I missed this thread.

Make sure the program is run with admin rights. Also, if it still crashes try to run it in XP compatibility mode.

it works fine for me... I use windows 7 64bit enterprise.

Yep sounds like securom sector. It's not actually and error, just the sector is a different mode than the rest of the disc.

What issue is protectionid giving you? It works fine here on 64 bit windows 7.

Sarami are you going to continue developing this tool? It would be great to get the C2 error detection/correction implemented.

Edutainment software is accepted.

Straight educational (adult, college, rosetta stone etc) has no place here imo... neither driver discs or OS or much anything else not related to gaming in some form.

cover discs from gaming mags accepted of course.

driver discs accepted if they contain games, or game related software (joysticks, steering wheels etc).

F1ReB4LL: the scramble.bin file I think is the EOR decryption key for scrambled sectors. IIRC it's nothing more than that to scramble a sector, there is no weird math like some people think.

We even listed the known working ones...

Moved to the Wiki, please check the list there.

In plextor it is dumping bad sectors as audio and they seem to match every time.  Don't know if data is correct or not, but I assume so...

for non plextor yeah 55 like clonecd and ddump. or maybe a switch to specify.

IsoBuster has had this mode2 bug for quite some time, don't bother using it for cue sheets.

DiscImageCreator.exe -rall d: 8 Track c2

This is the command I'm using from .bat

I think the problem is exclusive access is needed, IsoBuster was open but not doing anything. It worked again after I closed IsoBuster.

When device open fail error occurs, this is all I get.

There is no log

Ok, will give log next time I get the failure message.

As for splitting the log, yes. Drive, Disc, Error would be great. With more details for each, which track, was error corrected and with what method, etc.

Could you also make the log easier to read or split it up into different files.

DIC sometimes gives "Failure to open drive" error randomly, maybe look into that.

They aren't actually a bad sector with SecuROM , just an alternate mode sector. It's perfectly legal to do in the mastering process, it's just drives have pretty limited firmware most of the time and they expect every sector to be the same mode.

They are mode 2 sector without ecc/edc. Sectors can even have wrong header info, I have at least one disc with such.

SafeDisc are entirely different matter, we don't exactly know if what is read by drives (either plextor with d8, or other drive with audio trapdisc) is what is really on the sector or not. More testing needs to be done here with audio mode dumps to see if they match across drives or not.

Just because a drive can skip read errors, doesn't mean they are reading them properly. Also most tool just return made up data for them, usually filled with 00. For instance, CloneCD, Alcohol, ddump or other such dumping tool.

DIC should never match clonecd or ddump if dumped with Plextor (only!) drive. Don't bother with non plextor.

ddump is also buggy with safedisc 2.5 and up.

Also, thanks for C2 log!

Use plextor, dump with clonecd and also dump with disk image creator.

That stuff is bs with being able to read the bad sectors, the images will work if the sectors are just bad, not really what is on the disc.

As for burning, seems it's firmware bugs not being able to burn all patterns in proper order, the buffers get written to the disc in the wrong order but the data is there.

why would the raw read data vary from drive to drive ... that doesn't really make any sense. scrambling is not the complicated process it seems, it's just EOR of a pattern and I found that pattern in the firmware too. I think that was only an issue on very early hardware. I would like to have a dump of the disc done with an audio trap CD tho.

I also highly doubt they even know who the designers were, sounds like ripper BS to me.

Also, redump is about preservation right? It's not about "because it works"... or am I wrong? If it is... maybe I am in the wrong place.

Done some safedisc disc testing now. It is able to dump safedisc's bad sectors reliably. So far all dumps match on 2 different plextor drives. So far one disc , Daikatana, has been verified from 2 different discs (mine and DJoneK's). However, I think that such discs can ONLY be dumped on plextor drives.

This is both good and bad, the good is safedisc and probably laserlok can be dumped properly now. The bad news is all of those discs in the db need to be dumped again, or invalidated.

All tools just assume when burning, that track 1 has a pre gap of 2:00. Dunno why this is, or if you can even burn the real pre gap even if you dumped it in dao mode.

The cue/ccd is there to recreate the TOC on the original disc, if subs are burned too they can of course conflict with TOC like on many discs. Quite interesting how firmwares get around these inconsistencies. Protections could however check for these non-standard conditions... but rainbow books specs are rarely followed to the letter.

That's a bug in CloneCD

(3,497 replies, posted in General discussion)

I think it's more of a bug with the drive. Some drives have a problem reading "transition" sectors when one sector type meets another. In this case data and audio. This problem seems to happen when reading a disc forwards, if you start beyond the transition sector and then seek backwards to it, it should read ok.

Seems to be working now. =]

:EDIT:

I managed to dump some lead-in and pre-gap just fine. I do get errors, but the sectors are dumped anyways with subcode.

I did -5000 0 , but it only dumped 3927 sectors. I am not sure why.

I dumped some discs I have which have audio and mastering errors. It dumped the tracks just fine and they match my manual dumps. I will do further testing.

I dumped a disc with R-W filled with FF, and it was suffering the very slow reading speed. There needs to be some kind of switch to select which mode to read the subs as suggested to get around this.

Is the tool supporting C2 error reporting? Would be nice if it did.

I have not yet tried to dump some discs with intentional errors (safedisc, laserlok, smarte, sector header) I will do some testing on this too and let you know how it goes.

So far I am quite impressed with the tool! I hope you continue to develop it. It would be nice to add some more features like that of EAC and subdump for error detection and handling/repair.
