how to fix and repair hard disk drive










Received 1TB HDD for troubleshooting for not reading problem in desktop Computer.

hdd cannot read repair

Symptom: System showing error on Booting.

hdd cannot read fix

I have checked this HDD on another computer but the symptom is same.

Checked BIOS for detecting HDD in BIOS & found OK. So for further testing I have to remove the PCB of the HDD.

And on visual inspection I found very common problem for this type of error Gold plating contacts on PCB is oxidized.

As technicians always use the common trick for this problem is just taking a Rubber eraser and rubbing on the contacts. But as per my experience this process is temporary solution and you will get the same problem back in few days or months. So I have decided to try some another trick by applying solder on all the contacts.

(IF your HDD is still in the warranty do not attempt this process or you will void the Company Warranty on the Product) I have tried because this HDD is out of the warranty.

First I have cleaned the contacts by rubbing the rubber eraser. Then cleaned by applying IPA after drying the PCB I have applied soldering flux on the contact area and applied solder on the contacts and then cleaned it with Thinner. This trick is also applicable to Memory RAM gold oxidized Contacts by just taking care of layer of solder on it should very thin & of course memory should be out of warranty.

(Note: Use only 10 to 25W soldering Iron for this work or chances of damaging the PCB is very high.)

After completing the process I have put the PCB back on the HDD and connected the HDD to the Computer for testing.

    I tend to put silicone oil on such contacts to avoid subsequent corrosion after cleaning.

    Always a good thing to check all contacts. In the past there was a German firm in Holland that sold a special Gold writing Pen to renew worn out gold contacts.
    Sadly that pen can't be bought anymore. If I remember it well it only contained a few grams of Gold and did cost about 50 dollar.

      Hi Albert,

      Here is one that has silver.

        Thanks Robert. I opened that American link and it showed only one pen left. Strangely when I was asked to go to the European ifixit store the product search was lost and couldn't be traced either. Apparently ifixit now also has a store in the Netherlands but it looks like most products can't be bought.

          I thought they were only in the USA. maybe they are having website problems. I would try to call them and see what is going on.

        This product is good if you are having continuous work of this type.
        Because of shelf life of this product or may be your repair work would cost you more.

    Yea, that might save a few Hard drives I have laying around, but I'll try my ole trustworthy WD-40 🙂 lol it's magical"

    • Robert Calk

      April 6, 2018 at 11:19 am

      Yuck, lol. If you want a dirt and dust magnet it would be cheaper to use dirty motor oil.

    • Yogesh Panchal

      April 6, 2018 at 4:08 pm

      Some time "Magic" don't work.I have tried before.
      any way Good Luck!

      • Robert Calk

        April 6, 2018 at 11:11 pm

        That's right Yogesh, it gets all sticky and gummy. When I was a kid I wouldn't even put it on my bicycle chain unless I had nothing else! Had I used WD40 on my fans they would probably pull 1 1/2 amps and burn up. lol I think he's just messing with us...

    That is a better idea on how to solve the hard disk error

    I don't believe the contacts are Gold plated, certainly the ones I have 'cleaned' up weren't. In the early days of mainframe computers (70's) PCB contacts were 'tinned' (with solder) and they gave us continual problems - the next generation of plug-in PCB's were gold plated, and didn't oxidise, it was very rare that we had contact problems. If we did, then a LIGHT rub with a GREEN (Ink eraser) was all that was needed. Not too much as the Gold would be removed all together, now I prefer to use the 'Electrolube Contact treatment grease 2GAX' after cleaning the Gold Plated contacts (and indeed plain polished copper). It does all your suggestions and stays in place without oxidising - it's designed to fix exactly this problem.

    I believe the contacts are copper as gold does not corrode.
