Cleaning HDD Heads & Platters

Don't Lose Your Data Forever!

DIY data recovery has risks. You could lose your data forever! Don't want to risk it? Talk to a professional now.


I bet that green light doesn't show the smears/residue left from the cotton swab... or maybe it does.

Now I'm curious... bought a green light and will experiment with it. It would be nice to not have to have a fresh set of batteries in my LED flashlight just to see the tiniest specs of contamination.

The green light is interesting. The rest of it looks pretty much identical to the kit I got from Apex tools.

What type of green bulb is that?

Hello Jared,


On the other hand, in our tests:
Isopropyl alcohol (IPA) comes in different purities and uses. And this can make a "big" difference.

The one that gave us the most results is:
Degree H.P.L.C. (For High Pressure Liquid Chromatography).
From our supplier it would be: ... 26&titulo=

I agree with the issue of NOVEC, it is very expensive and difficult to achieve.
You can use the Novec 7500 to keep your investment from evaporating quickly. ... 334&rt=rud

Which has a Boiling Point Range higher than the Novec 7100 ... 247&rt=rud

We generally use the NOVEC, for the final process, or for head cleaning.

[post]14213[/post] Does someone of you know where to buy that cleaning tool or at least how's called?
I asked in the comments and the author replied
It's not about the frame sensor cleaning swab. It's the fluid i used. And this one is custom made.
Not much help, I'm afraid.


These work very, very well... at least in certain situations.

I do a lot of platter cleaning. When I read this post I was working with a dirty top platter of a 2.5" Hitachi. For something that should have taken 5 minutes I ended up spending at least 4 hours total on it and was only able to do a mediocre job... the ISO would dry into huge residue smears behind the wipe instead of "pull" along with the wipe and leave a spotless surface. Sure, you're always going to get nasty smears when swiping across media damaged areas, but this was a platter with only debris and absolutely no media damage.
After I developed a technique using the donor for this case, cleaning the entire platter on the patient took 60 seconds (using the same swab I cleaned the donor with).

Tried a swab on another case today--3.5'" WD. Platter securing ring had been grinding against dented-in lid. Contamination all over the place. Swab worked pretty well but I was able to do a better job, and more quickly with my normal method.

I will definitely keep a ready stock of these in my toolbox.
