Seagate momentus 7200.2 Hard disc failure

My laptop would not boot up, scrren said "operating System not found".
Hard drive makes loud continuous running sound but cannot access drive. Sent to recovery place and they said it needs to be reverse engineered with replacement parts, has physical failure.

Why can't I just buy a new drive, dismantle both and take the storage discs from the bad drive and replace ino the new drive, reaasemble and read off an external usb shell drive unit?

 

You can, but hard drives have 100% pure air in them - even the smallest spec of dust can destroy the insides. Data recovery centers have clean rooms where they work on hard drives. This is also why they are super expensive.

 

I know about clean rooms and the dust but they also wanted $2,500 to get the data. I am willing to risk the loss as it is not worth that much to me. My question: is it as easy as just swappin platters or do I have to worry about getting the eact same model or other issues?

Is it easy to remove the platter and reinstall or do I need special tools (I have never opened a hard drive).

Mine is a 120 GB 2.5 inch momentus 7200.2 drive. Could I use a different model momentus or do I need the exact model?

Is this even in the realm of possibility for me? Thanks for your thoughts.

 

More specifically, could I take the platter from my 7200.2 120GB HD and place them into a new 7200.2 200GB HD unit.

Is there anything else I would need to do?

 

It does not work that way. You cannot take platters from one harddrive, let alone a defective one, and place them into a newer harddrive. You can extract data from the old HD and transfer said data to another. HD internals are non user serviceable parts. You cannot do it yourself. You will also void the warranty on the new drive. Why would you want to do that anyway?

 

why dont u send it back to Seagate and let them repair it?

 

dude, just do it, and then show everybody how it's done ...

I mean I'd try it. The worst thing that could happen is that you loose another working unit and not recover your current one.

those data recovery companies usualy change the controller on the drive and that's it. Now depending on how bad the drive is, it may be easy fixable, or it may not be fixable at all (like if the head have hit the platers and scratched them then forget it on 100% recovery).

in case no scratch is present, the problem that you may have is that the tracks on the bad platter dont match the tracks on the other drive so that when you change platters, the new heads cant position exactly where they should, so you end up with nothing. Ok, that's little confusion, so let me try again: When you format your HDD, the heads position at some place and make a track, then move X amount of space and make another track. So how do you know that the heads on the bad drive have positioned say the first track on the exact place (distance from the center to the first track) where the the heads on the new drive have made a track on their platters ?

I do not know how much each track is apart from each other (see in wiki), but if the manucacturor has left enough space to cover inconsistancies in the head positioning, then the above may not be so big of a problem.

so just do it

 

I'd only due it if you can afford to reck another disk.

I 'reassembed' a hard disk about 6 years ago, but I have no idea how I did it...

 

Good luck, every time you take a harddrive apart it never seems to work again afterwards. At least that is my experience. The second you dirty that platter, you are destroying your drive. I recommend getting experts to recover your data. Its expensive but thats the price you pay when you do not back up your files.
