    I made a successful backup of my new Championship Manager 4 game using the Blind Write and Twin Peaks method but I've found it impossible to make a new copy of the copied disc. Why is this?

    The twinpeak method (as the 'burn RPMS info' method used by Alcohol 120%) is just an approximate copy of the original CD: the sector reading time (that is longer, for the original CD) is reproduced by burning two (or more) identical sectors one after the other.

    Such 'twin sectors' have the same LBA, which is a violation of the ISO9660 standard!

    For this reason I would be surpised if you could backup twice such a CD...
    but please note that this occurs only to SecuROM *New* 4.8x. There should be no problem to backup twice a Safedisc 2.x disc...

    [bold] I can backup a backup of SecuROM 4.8.x using BlindWrite 4.25 [/bold]. Simply read the image with sub-q data and store on your hd. Now create or download a "working" BWA file and save to your hd. Burn 1 image with the bwa file tucked in the folder and burn another image [bold] without [/bold] the bwa file tucked in the folder. I did this with ease m8.

    Shoey is telling you to create an 'install' disc (without BWA, needed to install the game) and a 'play disc' (with BWA, to be insterted in CD-ROM for protection checks and necessary to the game to play).
