So if I understand you right, I need a copy of BlindWrite on every computer that needs to play back a SecoROm backed up disc. I am asking because I have a Plextor Premium on my computer and on my kid’s computer an older SCSI Ultraplex Plextor CD-ROM drive. I was planning to buy BW to make up a backup copy of “Thomas & Friends” CD game that I bought for my kids to play on their computer. If I install BW on my computer and make a copy (protected by SecuRom 4.8x) then I need to purchase another copy of BW to install on my kid’s computer? IS there such a thing as a BW reader like Acrobat Reader that can be installed on other computers. I hate to pay for the software twice but if I have to then I have to.
Ok without sounding rude, let’s take this from the basics.
Firstly securom protected games:
Ever since from version 4.8x securom has manage to create a protected cd that consists of a physical key imprinted on the cd at manufacturing. In other words it has been stamped with a unique code (sector ranges) and whenever you play the game it searches to see whether or not these ranges are in the right place Also as an added level of protection the cd is given an atip checker which all cd-rs have (it’s a section on the disc that stores specifics about that type of media, ie manufacturer, size, etc) All cd-rs have them so by checking this everytime, a game can know if it’s a real copy (no atip) or a cd-r (with an atip). If it finds an atip then it will not work as it now knows the cd you are trying to play with is a copy. The thing about the atip is that, it is only writers who look for it as a cd-rom doesn’t need to know because it is only used when burning cds.
To cut along story short, if you play your copied cd in a cd-rom you will not need an atip “hider” but you will in a writer.
The plex premium has some fancy techniques that lets you make a near to perfect copy as you can with a securom image but because it cannot physically change a cd to the same ranges as the original cd it will NEVER be perfect (1:1)
Now on to safedisc 2/3.x:
This has the exact same atip checker as securom so again your backup will work in a cd-rom no probs (without outside help) but if you play it in your writer you will need the atip “hider”(commonly known as autoplay by blindwite, hide cd-r media by clonecd… and so on)
Other great features of sd is that it introduces week sectors (false information) that must be written correctly for your backup to work, hence the common terms “can write/almost write regular bit patterns correctly” (2 sheep burner, 1 sheep burner) or correct efm encoding" used a lot on this forum…
But that’s not the question here (that can be another lesson) Hope this helps, and by searching these forums you will find lots and lots of info about it.
