FriendFeedAdding Copy Protection
Posted

Environment: Visual C++
This copy protection scheme first requires you to detect bad sectors in the floppy disks. Then, four of the bad sectors are selected. Pressing the copy protect button will write a secret data file to the floppy disk that is the key disk. Then, to use the copy-protected floppy disk, you have to call the DLL file which reads the secret area and determines if it is the copy-protected key floppy disk. The DLL can be called anywhere in your program. You can even call it from Visual Basic.

What prevents the copy?
Posted by Legacy on 01/12/2004 12:00amOriginally posted by: Doctor Luz
This method is being used since many years ago.
The question is, what prevents an user to do a copy of the key disk?
Maybe an standard copy won't be successfull, but even in the old times of DOS I remember tools for copying key disks. And they worked very well.
ReplyFloppies.....whadaya talkin about.

I build PC's. If I didn't have system boot and driver floppies I'd be out of business real quick baby. Hell, even my not so out of date Sony digital camera uses a floppy. But the point is this guys code is for learning about one aspect of copy protection.

The LoadLibrary API fails to load disk32.dll eventhough the dll present in proper path. I am getting the folloiwng error in LoadLibrary
"The specified procedure could not be found"
Do u have the source code of Disk32.dll ? I need to verify the DllMain() function of this dll..
Did u get this dll from http://www.microcosm.co.uk/?? Because I have the same source and dll from them which exactly matches what you have published.
Can you please send me the source code for this dll or fix this problem.
I am running the application on Win2K professional. Compiled using MS-VC 6.0.

SPU
Posted by Legacy on 07/22/2002 12:00amOriginally posted by: Andre
11 years ago, when I was 17 I made a commercial software called SPU that formats the diskette, add some "bad" sectors to it, then even CopyIIPC crashed when trying to duplicate, that was my smart move, the stupid move, was that the aplication that you wish to protected must be infected(like a virus) with some assembler code i did, and this asm code check's out the floopy or harddisk searching for that special sectors...
It worked fine, still works, impossible to crack if you could not read the sectors, but didn't work for windows aplications 3.11(my stupid move)
But that was 11 years ago...
But anyway, you thanks for your code....

ReplySource for the DLLs

Where is the source code for the two DLLs you use? How do they read the floppies? With out this source I don't trust your code.
