3TB Seagate heads striking, need info on repairing

[jannerwingfeather]

First off, I do not have data that needs to be recovered on the disk. I'm just looking to make it work.

So I bought a Lacie 3TB external HDD at a rummage sale for a buck. I've powered it on, but the drive doesn't mount. It spins up for a few seconds, then there's a funny rhythmic scraping noise and it spins down. I've done a few google searches and it seems that this is related to the heads coming in contact with the platters.

Anyway, most of the information I've found assumes the drive has valuable data and tells you to send it to recovery services. Like I said before, I don't have any data stored on the disk, so I have nothing to lose but a broken hard drive.

Anyways, I'm looking for the best solutions on how to possibly get the drive to work.

Alternatively, If I am wrong about this, and there's some other simpler problem, please tell me, I haven't opened the drive yet.

Also, I am aware that any fixes would still leave me with an unreliable drive. I don't plan on using it for sensitive data.

HDD is a Seagate Barracuda 3TB desktop drive.

There's no standard series of steps to take for something like this because, if what you describe is accurate, it's purely a salvage issue, not a repair one. If you want to tinker and explore the internals of a hard drive, that's fine, but when the problem isn't a PCB issue but a physical problem with the platters, you'll have more luck reassembling a broken egg you dropped on the kitchen floor.

There is nothing you can really do since it seems to be a mechanical failure issue with the arms as the heads touches the platters.

The solution would likely be to replace the arms, but doing so is not a simple task that anyone can do. The drive needs to be opened to replace the arms. That where you will run into your 1st and most likely the biggest problem to surmount. Taking apart a hard drive for the purpose of repairing it means you need to do it in a cleanroom (or clean room); a room that is environmentally controlled to filter out pollutants like fine dust which can settle on the hard drive platter and lead to data loss or further physical damage as the fine dust scrapes along the surface of the platters. You would also need to find replacement hard drive arms; presumably from the same make and model of the hard drive.

The best thing to do is to chalk it up as a loss and buy a new hard drive which will come with a warranty.
