If you’re like me, you’ll undoubtedly have messes around with a fare share of computer hardware, and like me, if you come across a fault, you will want to diagnose and fix it yourself. This is fine for a lot of things inside a computer, but one area which you should stay away from is hard disk drives. This is not because you don’t know what the fault is or how to correct it, but because the amount of misinformation online is incredible.
First things first, hard drives are such an engineered device that it can be difficult to know what fault a drive might be suffering from specifically. This is one reason why it is not recommended to diagnose a hard drive yourself. If you take for example, a mechanical fault such as a head crash, it can be very hard to actually determine yourself if the drive has a head crash or not, this is because every manufacturer of hard drive make them slightly differently, and furthermore, each specific model of hard drive makes different noises, these can be hard to recognise.

What’s wrong with DIY fixes?
Misinformation. The amount of false information on those kinds of sites is absurd. For example, some sites recommend putting the hard drive in a freezer. Does anyone see a problem here? Well, if you put a hard drive in a freezer, it won’t do it any damage until you take it out of the freezer. You will instantly get condensation, which due to the sensitivity of the platter’s magnetic coat; it will cause instant damage to the platter (your data). This is just one example of falsity in hard drive fixes.
Let’s take another example, a hard drive has stiction, a common fault on 2.5” drives, lets hit it to release the stiction. Removing stiction is a very delicate procedure that should be done in a place with access to a clean room. Because stiction is a fault that involves taking the drive lid off, it should definitely not be attempted by a home user, you would (if the data is important to you) take the drive to a reputable recovery company that have a clean room. While you can release the stiction yourself, if you do not have the training, you could rip the read/write heads across the platter which will grind away at the platter and destroy a lot of data!
DIY fixes for hard drives do not work. You have to add it up, is the data on the hard drive (that could contain precious photographs, documents and music) more expensive than choosing a professional data recovery company to go with.
