DiscImageCreator (Page 5 of 141)

fixed

That's a bug in CloneCD

I agree with Nexy, the missing INDEX 0 for Track 1 is a bug with CloneCD. The .cue files here on redump don't have an INDEX 0 for Track 1 when INDEX 1 is >00:00:00. This should be fixed.

I noticed that the last track for my disc is being underdumped. The last 30 sectors are lost with DiscImageCreator and not with other tools.

Thanks! I tested it and everything is working fine

I sent a message to iR0b0t about the redump .cue file issue.

Here are some DVD dumping issues/requests:

Only L0 is dumped on the following disc type (example):
TrackPath: Parallel Track Path
NumberOfLayers: Double Layer

Checking for "PhysicalFormatInformation: L1" will probably fix this issue.
Opposite Track Path DVD-9 discs are also being overdumped.

Could you please add TOC+Layer Information:
Session 1... (LBA: 0)
-> Track 01  (Mode 1, LBA: 0 - 4169567)
-> LeadOut  (LBA: 4169568)
Layer 0 Sectors: 2084944
Layer 1 Sectors: 2084624

IIRC the drive reports c2 errors on those sectors, so who's to say that the data is dumped 1:1 and it isn't some pattern that is unique to plextor drives (otherwise why do audio trap dumps on non-plextor drives give different data)? I'd rather hear first what truong and ripper discovered in their research and how they implemented safedisc dumping into trurip (afaik they talked to the designers). And is there any real point in redumping all these hundreds of discs (many of which will be unavailable and have to be bought again)? Error sector = error sector and I doubt it can be burned and then dumped again 1:1? And then we also have to redump all SafeDisc etc. DVD's into RAW? 

Back in the day you had so called sheep burners (referring to the CloneCD mascotte)

I googled somewhat and found:
Here are two drives capable of reading the weak sectors of Safedisc

http://www.cdrinfo.com/Sections/Reviews … p;PageId=4

They in turn produce a working copy when burned back to disc. (without using protection emulation) Look up your own drive for capabilities. (maybe we should make our own chart?)

There was a chart ones, but can't seem to find. (which reader / burner was good for dumping)

My guess is these versions are the same:
http://redump.org/disc/10567/
http://redump.org/disc/18847/
But produced different hashes due to the drive being used. I tested my dump using Daemon Tools without Safedisc emulation. Do not know if Nexy did this aswell. (or anyone else tried)

As far as I know there is no DVD drive capable of dumping DVD protections correctly

I still have the discs. Dumping it now on a different drive. I am not sure if I did this back then.

Now I know why I did not do it. Unable...DDump won't let me dump it on my LG drive. Isobuster comes up with a replace sectors message which you should not do if I am correct.

I checked my logs and game was dumped twice on my Plextor

You could check the bad sectors in cdmage to see if they contain the 0x55 pattern?
If not, then changing those sectors to 0x55 should match up Nexy's dump if it's the same.

Same hashes as cloneCD dump indeed. (different drive) Weird to me. Why were there crackers back in the day when they just could have used clonecd? The only reason I can think of is that a lot of burners couldn't write such an image properly. As posted in the above forum link.

Safedisk 2 has a few sectors in them which were designed to not be writable (due to overloading the writers EFM encoder).
However, some writers were capable of doing this still in those days.
Nowadays, I think all writers are fast enough to be able to do this.
In any case, these are not the bad sectors which you get on read, those are a reading protection (the idea was to make dumping the disk take ages)
Also, safedisk 2 was devised in a time when disk emulators like daemon tools and alcohol were not invented yet (or just barely invented).
