Some time ago I bougt usb external backup disk with 2x ST3000DM001 3TB. I had them in my NAS for couple years but after some time I started to get info about bad sectors. One drive had gone from the system and second was working without problem. I took them out and didnt use them for around a year. Yestarday I copy data from one drive and started with second one. Unfortunately he didnt want to work - problem is the same like on this video https://www.youtube.com/watch?v=rGBWlNtubnA - it spins up, move head couple times and stops. I swaped bios from first working hdd to check is it going to work but it is still the same ( connected by usb hdd case or directly by sata to pc)- spins and stops. What should I do to make it work? Should I swap also the head or some other part? I'm curious if I can recover data some home way (I won't need them anyway and I don't even know what is on that broken hdd)

You did wrong

The ST3000DMxxx acts like you say when heads are bad

More in general, when Seagate drives do click and stops , heads are bad

Except some particular rare cases
when a Seagate drive makes repeating sounds after spinup , its heads are bad

What is worse is that Seagate drives made after 2011 , when issues begin, go worse and worse in few spinup attempts

In short drive heads are gone, if there is critical data that you want, must consult a DR Pro.
These DM series drives as already mentioned are really bad drives.
