FW: Need a software to copy my floppy

Here's how I go about copying those "un-copyable" floppies: 1) First, try using dd(1) on some unix-like system (linux, OpenBSD, etc) 2) If that fails, get some hex-editing software that can modify a block device. I believe that "biew" or ncurses-hexedit will do this, both of which are available for Linux, may be compiled on others. 3) Print out a screen capture of the first sector of each floppy after You have used dd. Compare the screen shots. It may take 2 or 3 screen captures to get the whole first sector. 4) Use the hex editor to modify bytes on the copied floppy, so that it EXACTLY matches that of the first. I don't believe that dd(1) will copy over the serial number of the floppy disk, and it may not copy over the "OEM" Field, either. This makes these two areas of the floppy diskette "Prime Pickings" for copy protection. I used this method to make a backup copy of "Game Guru", a game-hacking program for adding points, live, etc to saved-game files such as DOOM's saved games. It's quite old but most floppy-disk copy protection uses this method (from what I've seen): HINT: If the Serial number shows up in DIR as "5F31-8E4F" it will be in hex on the disk as the characters "OŽ0_" which is in hex "4F 8E 31 5F", the bytes are exactly reversed from the serial number. The OEM Field usually reads something like "WIN4.0" or something. If I had a machine in front of me, I'd give you byte offsets for these two fields. I hope this helps. --Noah Dunker -----Original Message----- From: Erick Arturo Perez Huemer [mailto:eperez () GRUPOTSLC COM] Sent: Tuesday, October 17, 2000 5:57 PM To: VULN-DEV () SECURITYFOCUS COM Subject: Re: Need a software to copy my floppy You are using a program that has been protected by a software called Copy Control. The ccmove.exe and/or ccmove.dll applications are in charge of "transferring" the authorizations/keys to use the software to your hard disk. If you use normal "copy" procedures..the floppy will not work. You are not supposed to be able to make a copy of that floppy because you will violate some copyrights of the program's company. Yes, I know you want to make a backup copy..you're out of luck. Contact The vendor of your program for a backup disk (they will charge for sure). Try DiskDupe, or DiskControl Anyways, those tools are designed not to allow you to copy the floppys. There were some copy programs that allowed you to copy those kind of disk...if you can get your hands on one that works with the new versions of CopyControl, let me know... Erick A. Perez H.
