Hello and thanks to anyone who will bother to read.
I have this 1TB Seagate Barracuda that makes strange noises at boot, but after a couple of minutes it does the loading sound "vvvv" and becomes readable via usb.
It used to be readable straightaway.
Here is a video that shows what happens, by some coincidence it does the loading sound "vvvv" and becomes readable via usb exactly when i place my hand on it, minute 1;05
