I have heard the term "key disk copy protection" thrown around here in a few articles. Does anyone know what this protection scheme is? I can't think of very many copy protection schemes that a raw track read and write could not circumvent. I would be interested to know how people like EA copy protect disks. Dave Scidmore

The key disk may be removed once the program has verified it. Thus, if you have a hard disk, for example, you may copy the program to the hard disk, and run of there, only inserting the floppy when you start the program. If the manufacturer is reasonable, and you start the program without the key disk, it will ask for it, verify it, and then eject it. If the manufacturer is a jerk ( Electronic Arts ), the program will just crash the system. I complained to EA about this, and they told me that it was a feature. ( This is on the Mac. I don't know what they do with their Amiga stuff ). -- Tim Smith sdcrdcf!ism780c!tim || ima!ism780!tim || ihnp4!cithep!tim
