If the standard deviation of the random errors in the data is disadvantages of weighted least squares: is probably the fact that the theory behind this method.

We will not sum the individual errors, but their squares this way, all of them will be positive, and to minimize the sum all of them will have to tend to 0 this is why the method is called least squares, because it tries to find the line which produces the least squares of the individual errors.
