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.

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...

Asunto: Need a software to copy my floppy


Hi I have a floppy which is copied by a software named ccmove and now I
need to make a backup from the floppy but I can't because it is protected
by ccmove so my question is "is it any way to make a backup from my
floppy?" regards
 Sh
