Rectifying SubChannel data?! Whats that do?

Machina · #1 07-01-2004, 19:55

When SubChannel reading is enabled in BlindWrite or Alcohol 120% - I can choose to RECTIFY SUBCHANNEL data. Is it the same thing as fixing WEAK sectors in BlindWrite?

I know that doing so makes the image NOT 1:1, but for my Playstation backup - the CD backup works a LOT better when I enabled the RECTIFY option.

What does it really do?

Also, another question out of whack - is it true that newest Alcohol 120% can make working (or is it 1:1????) SecuROM 5 and below images? The previous version could not read SecuROM 4.87 correctly for even a working backup.

About your Playstation disc. Use Alcohol Playstation profile and you see the settings. Alcohol can handle Blindwrite files!

About SecuROM, I only have heard, that newest Alcohol can emulate SecuROM, never heard if they can backup it, but think you can! RMPS I think the name was, has been fixed....dose people say. But I can't confirm on that!

Rectify subchannel = correct "bad" subchannel data. Some protections used to have bad subchannel data as a part of the protection...a cd-writer then might correct the data and the protection finds that it is a bad copy---> b00m*

...another plate to put the cold beer on.

Ah, but if the subchannel data is NOT a part of the protection - should it be corrected?

Well, if the subchannel data is normal then it's should be ok and there's no need for it to be corrected...even if you check that setting, I think the program will ignore it since it's already ok.
