How to Recover Data From a Broken Hard Drive

You are reading this... you are probably desperate, but before you panic let me tell you that there is hope, and there is probably more hope than you think…. Even if your hard drive has an internal mechanical malfunction, data can be recovered without having to send the hard drive to a data recovery service. Yes! you heard right, I’m sure you have come across articles that will tell you how to recover data from a damaged partition, you will find a ton of those on the web, but when your hard drive starts malfunctioning none of those articles are going to help you solve your problem, This article will.


Corrupted file system
If the hard drive gets detected by Windows and can be accessed but you do not see any data inside, or you get a message saying that the drive needs to be formatted. You probably have a corrupted file system in you hands. The solution for this is a good file recovery software. I’ve tried many, and my choice is “Recover My Files” from GetData. Many of the recovery suites out there claim that they can recover data and they probably can, but can they find everything that you want to recover? Most likely not! This software can. But don’t take my word for it, download the free version from their website and give it a try, you will see what I’m talking about. The free version is a demo so it will not allow full functionality but, it will let you see what it can recover and will even let you recover some small files. This software is included in my article: Best Data Recovery Software.
The software does have its drawbacks. If your file type is not on their list it basically can’t be recovered. If you want to recover a file with an uncommon extension that is not on their list you are out of luck. Their list is extensive though. Make sure you run the “complete File Search” and not the Fast, as the later is basically worthless. The complete will give you more than you need, even stuff that you erased from your hard drive years ago. It will take a long time depending on the size of the hard drive. The program will not allow you to install it on the same hard drive where the data needs to be recovered from for obvious reasons. So be prepared to install the software on a secondary drive like a USB Flash Drive or External Hard Drive. There are also a free alternatives which work as well or even better than “Recover My Files”. If your disk read my article: How To Repair A Damaged Partition or MBR. If you are unable to recover the damaged partition but still want to recover your files, read my article: How to Recover Erased Data Using Free Software.
Clicking noise of death
If your hard drive is making the common “clung… clung… clung…” sound your head are having trouble reading the contents of the drive. This is one of the worst problems you can have since the arm of the drive is not functioning properly and therefore cannot read the disks inside. As some of you might know this is not repairable, at least not at home, Hard drives need to be opened in dust free environments, and by specialized personnel, so do not even attempt to open it if you want your data back!!!. Many people will just give up at this point and send hard drive to a data recovery service. However, before you do that and spend an arm and a leg, there is something you can do.  I have written an article just for this: How To Recover Data Even When Hard Drive is Damaged

Hard drive does not get detected
If the computer does not detect the hard drive, or the computer just does not want to turn on when the hard drive is connected to it, you might have a bad hard drive board. This is the big circuit board located at the bottom of your drive. These easily replaceable boards tend to get damaged over time due to the heat generated by the hard drive itself. I will tell you how to replace this board with the following solution:
There are a number of places on the web that will sell you these boards. If you can’t find it or you are a cheap bastard you can always resort to eBay and buy a used hard drive with the same model number as yours, remove the board from the used drive, and use it on broken one. This will probably cost you less than purchasing the board alone. If your hard drive is old it makes more sense to buy another hard drive, on the other hand if the hard drive is new you are better off buying the board. These boards run around $50 each. If you decide to purchase another hard drive or the board alone, make sure you are getting the exact same board! I cannot stress this enough. You can have drives with the same brands and specifications with slight variations on their board and consequently on their firmware, if this is the case the board will not work, so make sure you are getting exactly what you need before pressing that “buy now” button!


Hard drive gets detected but still does not work
If Windows detects the hard drive but it can’t be accessed, won’t give you the option to format it, or its properties. You probably have dirty contacts on your board. Usually when this happens you do not hear the famous “clicking noise of death” noise, but rather a repetitive “rrrrrr rrrrrr” sound, as if the hard drive is reading the same data over and over, or you do not hear any sound at all. It is important to mention that this behavior does involve the computer detecting the drive but DOES NOT involve the “clicking noise of death”. To solve this problem try the following: Remove the main board from the bottom of the hard drive and clean the bottom contacts. That board that you see underneath the drive is actually sitting on top of un-soldered contacts. Many Hard Drives operate at high temperatures, and this tends to melt the circuit board’s coating. When this happens this coating will spill over these contacts, and since they are not soldered their dirty metal surfaces will no longer touch. To solve this, remove the screws from the board and flip it. You will see a row of contacts usually in more than one location. Rub the surface of the contacts with a pencil eraser, just as if you were erasing something you wrote. This will actually clean those contacts better than any other method. Screw the board back in place and try it. (If your hard drive happens to have pin connectors rather than flat ones, disregard this tip and buy a new board.)


Clicking noise of death (Last Resort Solution)
This trick will actually work 60% of the cases, so you do have a good probability of getting your data back. I have to warn you that after freezing your hard drive there is also a good chance that the hard drive won’t work ever again, therefore this procedure should only be attempted as a very last resort.

1Place the Hard Drive inside a Zip Lock bag and put it in the freezer for about 2 hours.
2 – After that take it out and connect it to the computer as fast as you can so that it does not have time to warm up. Make sure that you do not remove the hard drive out of the bag and that you open it as little as possible when connecting it to the power and data cables, so that outside air doesn’t come in and create condensation on the drive.
3 - Turn your computer on, look for your data and take it out as fast as you possibly can. Time is key here because you do not know if that drive is going to ever work again. Make sure you do this on a fast computer that does not take to long to boot up, if possible connect the hard drive to an external USB enclosure so that you do not waste time with the computer booting up. Also make sure you know the exact location of your data; is better if you go to straight to the folder rather than using Windows search utility, as searching the drive will heat it up faster due to the amount of work the arm will have to make. Drives usually work for a few minutes and stop working once they heat up. So hurry!!!
4 – If after freezing the hard drive and connecting it to the computer you are still not able to access it and you still hear the noise, hold the drive in your hand and, without taking it out of the bag, tap it with your knuckles on one side to see if this releases the heads, you obviously have to do this while the hard drive is powered on and connected to the computer.


Final Thoughts
If none of these tips work for you and you still want your data back is time to send your drive to a data recovery service, there are number of those on the web, I have never actually tried one, but some of them will charge you a flat fee regardless of the problem. However, these services will not guarantee your back all of the time, in fact most of them regardless of what they claim, will just have a 75% to 80% success rate. There are some things you just can’t recover from, like an arm scratching the whole surface of a plate. Best thing is to back up your data regularly.
