I think that's not fully correct.
the minor scale is basically a major scale starting at the 6th note
That would be the
natural minor scale aka aeolian mode.
The harmonic minor is like the natural min but with the seventh degree raised on semitone.
Natural minor: 1 2 b3 4 5 b6 b7
Harmonic minor: 1 2 b3 4 5 b6 7
So the chord progression in harm. minor would be:
min,dim,min,min,maj,maj,dim
Hope i got that right...
