if (GETWORD(buff, 0x0b) == 0)
{
     /* what to do about this?? */
}
else
{
     nsect -= GETWORD(buff, 0x0e) + buff[0x10] * sz +
             (GETWORD(buff, 0x11) * 32 + (GETWORD(buff,
              0x0b) - 1)) / GETWORD(buff, 0x0b);
     if (buff[0x0d] == 0)
     {
         /* what to do about this one?? */
     }
     else
     {
         nclust = nsect / buff[0x0d];
     }
}

Now, how come those values become zero? I don't know, so I can't fill in 
the missing stuff there

HTH,
