Replacing platters on WD3200BEVT

Hi guys. I have a WD3200BEVT hard drive and I have the problem "spindle stuck". So a friend of mine told me to buy the same model of hard drive and change platters to get the data. Data is so important to me, and warranty is still valid. So I want to get the data, then send the computer to warranty service. I found the same model of that disk. Its platters have some bad sectors but spindle is working. And I got it today. But the problems are;
-I'm not sure if it's really gonna work.
-I'm not very experienced about hard drives and I don't wanna fail.
-I don't have much money to take it to data recovery services.

And I don't know which size of hex key I shall use. Can you guys help me with that?

There is 0 chance of you swapping out platters in your house and having it work or be stable to hold data.

The best you can do is take it apart to see what the inside of a dead drive looks like.

Plus soon as you open it, all warranty goes out the window so you won't be able to even get a new drive.

The whole point is that you can't do it safely. Not without a clean room and a lot of other equipment to align the disks.

You see anything like this http://www.masterfile.com/stock-ph [...] -Singapore at your house?

Not a good idea, but it's your disk and data to try with. Size of the equipment you need will vary from vendor to vendor, pop it open and see what you need. Or do a web search for your model and see if someone has put together a list of tools needed.

Don't you think I'm kinda hopeless and trying to try my best?

As I said before, feel free to try this, it's your drive and data. Juggling live grenades while in a tank filled with sharks also has a chance of working out if you're very lucky. You can drop all the grenades before the timers are up, the sharks will eat them and blow up, you're safe.

You're really trying to find a place that will say this is a great idea to try, so may as well go for it.
