I tracked down the error message.  It's coming from this piece of code

             sprintf((char *)tmpString, "P %ld %ld\r\n", Sector, Sector);
             SendComPort(tmpString);

             ReceiveComPort(Answer, sizeof(Answer)-1, &realsize, 2,5000);

             sprintf((char *)tmpString, "P %ld %ld\r\n0\r\n", Sector, Sector);
             if(strcmp((const char *)Answer, (const char *)tmpString) != 0)
             {
                 printf("Wrong answer on Prepare-Command (2) (Sector 
%ld)\n", Sector);
                 OutputErrorMessage(GetErrorNumber(Answer));
                 exit(4);
             }

The prepare command is documented as taking a start sector and an end 
sector number and so something like

P 2 2

should be sent to the micro.  Unless echo is turned off then that should be 
echoed back followed by the return code number (which should be 0 for 
CMD_SUCCESS).

It's apparently not getting that but the code is converting whatever is 
received to a number and then to an error message.  If you can compile the 
code try inserting the following line

printf("Expected [%s] -- Received [%s]\n", tmpString, Answer);

That may help track down what is actually happening.
