Question HDD beeping/not visible

[Rasepi]

I had an old Seagate 1TB HDD before this one, and it started beeping and not registering.
I thought it was failing so i bought a new one literally 10 days ago, so its brand new.
Same problem occures...Sometime it's visible, sometimes not...When it is visible, it's making this beeping noise whenever i try to write/download something on it. I tried connecting it to different ports, but it didn't work.
Btw, this is Seagate Barracuda 2TB.

Update your post to include full system hardware specs and OS.

Any pattern to the beep (beep codes): some combination of long and short beeps?

Try new/known working data and power cables to connect the HDD(s).

Should i run an dxDiag and send it to you? Pattern...Maybe short beeps when i try to write/download something onto it?
What cables should i try? I have SATA cables connecting the HDD to the MB...Could it be that they are not supplying it with enough power?
