Ya you are right but there are couple of reasons I did not use that1) adjustment of speed cannot be achieved 2) it rotates at quiet modest speed and putting a bit of load on disk will stall motor from rotating 3) not all HDD have constant rotation system some may spin some may not and some may have that circuitry damaged so I went with this setup which serves the purpose very well. Thanks for your time and interest ✌️👍🙏😊
i wander even if you (the one who got idea) has knowlage to run like you said!???. i mean you not even know which part is the motor controller. i bet that
