I think the problem is here:
else
{
perror(file_name);
exit(-1);
}
"perror" prints the file name followed by the latest error code, which happens to be "Success" or no error.
This is happening because its getting to the end of your file before the required 2048 bytes have been read.
You need the ".org 2048" !!!
