  Thanks for the update. The error seems to come while seeking(fseek(3)) to fix the file pointer at the end of the file, just before adding required padding to the iso.

    if (fseek(fp, isostat.st_size, SEEK_SET))
        err(1, "%s: seek error - 6", argv[0]);

    memset(buf, 0, padding);
    if (fwrite(buf, sizeof(char), padding, fp) != (size_t)padding)
        err(1, "%s: write error - 2", argv[0]);

Strange, that it should happen. I guess, may be, HPA could be better able to explain why it should happen for 2G files.

Can I have the iso file?

Thank you.
