Gpio indicator of drive activity possible?

[Mentaluproar]

I want to have an LED connected to the rockpro64 via GPIO. I want it to stay lit but flicker when there is activity over SATA. I saw there was an old pi project on GitHub that did this but I don’t think that will work on a pi. 

I’ve looked around online but the best I can find is controlling pins with an obsolete method. Something prior to the character device we have pins presented to us now. It didn’t explain how to make it indicate anything either. 

Has anybody done this before?
