Hello everyone. I recently got four SATA 500GB 7200rpm HDD and a 250GB 7200 rpm WD HDD. The latter one when I connected to my PC it spins for a while and then there is some clicking noise and so kind of grinding noise. It does not get detected on my PC too. So I tried to use the HDD to make a stepper motor driver. Used the SATA power connector I had previously salvaged from an old suply and connected the Black-Yello:12V and Black-Red:5V. The HDD was spinning for a while and then it stopped spinning and the cycle continues. I measured the voltage across the HDD Motor terminals and it reached a peak of 3.8V and keep falling to 0.5 and then rises to 3.8V again. I have a bunch of stepper motors I had salvaged from printers, Floppy, DVD drives etc. So, is it possible to make the circuit run a stepper motor continiously? Like any circuit modifications to make it happen?
Thank You,
Cheers
