cactus data shield 200
 

How can I copy a cactus data shield protect CD? excuseme for my english!!There isn't any italian???

i haven't done one of those but you can get a prog called clonyXXl and use that to scan the cd and it will tell youwhat settings to use to copy that protection using CLonecd

you will find it in cdmedia worlds site....

OK

did you get it?

yes, but my yamaha crw6416 doesn't supper the SAO!!!!there is another way to copy the cd?
There isn't any tutorial to copy a cactus data shield cd?

try a google search...

I've alredy try it!!But i didn't find a good tutorial!

try using the copernic tool...it has all the search engines.....

What is copernic tool? where i can find it?

Search Google for it - I don't really like it that much

well,i don't really use this a lot but evrytime that i can't find something by searching at the sites of the search engines i try this tool...

I 've burn it with plexwriter!!

Hey, above some guy mentioned that his burner did not support SAO copying. I just wanted to know how SAO compares to DAO copying ?

My TDK VeloCD supports DAO RAW but I always noticed in the CloneCD settings that it did not support SAO.

So if you could, plz just gimme a little info on it :)

I don't know anything on it!it isn't my! it my friend's burner!

SAO-RAW:
Besides the standard RAW methods that are mentioned in the MMC standards we also have SAO-RAW. SAO in this case is not the same as Session At Once and therefore it is not an MMC standard!

Than what is SAO-RAW? SAO-RAW is nothing more than a software trick to get errors from the original disc onto the copy or back-up. This trick was first used by Wesson, creator of BlindSuite (www.blindwrite.com). Programs like DiscJuggler (www.padus.com) have used this method since the beginning to copy the 'unreadable' sectors. Unreadable does not mean that the writer cannot read the sectors, but it means the sectors are giving wrong (not compliant to the standards) information to it so that the writer will keep re-reading them and eventually will enter a "0" for these sectors.

If you want to back-up an error protected game like a game with the SafeDisc protection (which has about 10.000 error sectors in the first 5% of the disc) and the writer fills in a "0" for these sectors, the back-up will not work! The game has a build-in check to see if the error sectors are present and if they're not, it simply won't start and give a message like "Please insert the original CD"...

To prevent the writer of filling in a "0" for the error sectors a smart trick is used that works in the same way as an audio disc being written. To explain this we have to get a bit technical:

-A CD-R of 650MB has 333.000 sectors
-Each sector can hold a maximum of 2352 bytes

But here's the trick: a data sector can only hold 2048 bytes per sector! This is because a data sector will have space left for the error correction (so-called CRC-check). An audio sector does not use the CRC-check because audio is corrected by the hardware and therefore it can use the full 2352 bytes per sector!

SAO-RAW uses this to write 'data in an audio way' preventing the writer from doing an error correction and therefore it will write the errors on the back-up and thus producing a succesful copy.

this was a good one safedisk!!!
