Diagram of hard drive?

By EStreetJerseyGirl ·
Hi! I have a 12gig Quantam Bigfoot TS12.7A hard drive, and it had a head crash. I want to fix it, and have the instructions on how to do so, but the only thing I would like to have before I go putzing around with this is a diagram of what's where on the inside of the drive. Can anyone point me to one? I tried searching on Google, but no luck there.

My best suggestion would be to see if you can get a junk drive from a local computer store to take apart and practice on.

The basic mechanical assembly is very similar from drive to drive.

Now, what do you have to prevent ANY dust from getting into the drive when you are working on it?

Any dust or dirt that gets onto the drive platter will negate your repair efforts.

Hard drives are assembled in class 10 or better clean rooms. (Clean room class refers to the size of a particle in microns that could be found in the room.)

You need at least a clean area away form ANY forced air flow with a static de-ionizer running to have a chance of a successful repair.

Thanx; I never even thought about having to have a hermetically sealed room to work in!

Think I'm just gonna give the drive to our son and let him putz around with it.

Once you get inside you will realize it is not that hard. Use a digital camera and photo as you go.

Your problem is going to be building the box to create a clean enviroment.

Years ago when some drives were in the thousands instead of the hundreds we built one out of Lexan.

It looked a baby incubator. Gloves attached and all.

We used respirator filters attached to muffin fans to put a positive pressure on the box. There were four on one end. On the other end was a spring loaded flap that allowed the pressure to escape.

You put the drive, tools, and parts in the box and sealed it. Turn on all fans and wait for a while. The 4 fans would stir up and flush out all of the fine particles of dust and dirt. At least that was the theory. Once we thought it was clean we could turn off three of the fans. One would provide enough air flow to make a positive pressure.

We actually did manage to extend the life of some drives long enough to get data off of them.

What we are trying to tell you is that you are going to spend a lot of money and time to fix a 12gig drive.

The contamination that will crash a drive is not visible to the naked eye. To a drive head a human hair looks like the holland tunnel.

If you like to tinker and love a challenge go for it. Don't expect to get pop the top replace a head and get dungons and draggons going again.

Good Luck Lee

Love the Holland Tunnel reference!!

Thanx; I think I'm just going to give the drive to our son and let him putz around with it for the **** of it.
