Hi guys! I have an external Seagate ST3000DM001 Barracuda 3TB drive that stopped working a couple of days ago. When I plug it in it sounds like it's spinning up then makes strange noises for about 20 seconds then quits. Sometimes it beeps a couple times at the end. It is not recognized by my iMac or Macbook Pro. I've opened it up and the top disk looks perfect. The arm was off to the side (not sitting over the disks). I'm not sure what the problem could be. Any help would be greatly appreciated. Thanks!

Here's a link to the video of what it's doing. (Hope I know how to do it correctly)

It's a mechanical damage, very likely heads are faulty.
If you need to recover data you have to send the drive to a PRO.

It could be pretty expensive because you decided to open it, platters decontamination is needed also.

Sorry, it's not a DIY case.

did you mean you open HDD in none clean room environment
this is not DIY case
and if your data is important for you
so it's not time for experiment
and you should go to professional DR
