Working with a computer on a daily basis, either because it is necessary in our profession or because you have it for fun, can lead to the fact that we end up having some kind of problem like hard drive crash. Is it difficult to repair a hard drive? It is always advisable to turn to a professional if we are not sure what is wrong, but sometimes its repair is quite simple and requires a series of steps which we will give you below to know how to fix it yourself – even a hard drive.

Repair a hard drive yourself


How do we know our computer hard drive is broken? You may have noticed that your computer is slowing down or making a strange noise. It also happens often that you ‘hang’ or just don’t turn on for the problem to be located on the hard drive, so you should know if it has a repair, if you can retrieve the information you had. stored (which it will be backed up in the case of having made “backups”, and especially how can we make it work as before.

We are going to see a series of steps that we can apply to repair a hard drive on our own, although if you have any doubts or are not able to do so, we advise you to consult an expert.

1. Confirm hard drive status

Check the fault

Easy. You need to pay attention to one of the points we highlighted earlier, if you notice that your computer is making a noise (and that it is coming from the disk), is that the unit has a fault, it may or may not be serious.

The first thing to do is to restart the computer to see if the noise persists (sometimes when we have the device without ventilation or full of dust it may make noise but then it disappears) if it does, you have a problem in the disc.

Checking the hardware connections

Many times our computer’s hardware connections fail and we think what happens to us is that our hard drive is dead. First check that the computer is receiving the correct current, sometimes a loose cable can cause us to think of the worst.

Once you’ve verified that the electricity is coming in, you need to open your computer chassis. Check inside that the data cables (identified as IDE or SATA) are properly connected, that they have not come loose and especially that you do not have any bent, broken or damaged connection pins of another way.

Visually check the entire interior

Once the computer is open, and even if you think everything is a meaningless wire harness, you need to make a visual recognition of it:

  • See if you have some kind of burn on the inside of the computer board. A spark may have been triggered and the PC motherboard, not the hard drive, has been damaged. If so, you have a problem because you will need to fix it, although it won’t be as bad (or as expensive) as losing the hard drive.
  • You need to buy a new card and replace it with the old one. To do this, remove the damaged card (do not lose any screws) and be careful not to touch the metal parts of the new card so as not to give it an electrostatic discharge that will damage it before inserting it (you must put it in earth with an antistatic wrist strap or touching something dirt or metal).
  • Slide and insert the new card, making sure it is firmly seated in the reader, then replace the screws.
  • You need to reconnect the device to your computer and turn it on and if it works, you will have solved the problem! Otherwise, you will have the last step.

Check if the device is recognized

If everything is plugged in and nothing is burned, you need to check Windows Disk Management or BIOS, or Mac OS X Disk Utility, to determine whether your disk is recognized by the drive or not. Otherwise, you need to reopen your computer to start repairing the hard drive.

Test the hard drive

How you have decided that you yourself are going to be the one distributing your hard drive, you have to take it and hold it in your hand. Turn it back and forth to check that you hear noise. If you hear anything, it means you have a bug which in most cases can only be fixed (sorry) by purchasing a new album. If you don’t hear anything, this may have a solution even though it’s an album that has been around for many years.

Heat the disc:

Preheat the oven to its lowest setting for about five minutes and turn it off. Place the appliance in the oven for 2 to 5 minutes until heated through.

You need to remove the disc and repeat the first step. If you can’t hear anything, you should reconnect it to your computer and pay attention to the noise produced by the disk spinning and the normal clicking noise that indicates head activity. If everything is going well so far, try to access the drive and transfer your data to a drive that works well.

If necessary, warm up the device, then check the noise. One solution, although somewhat drastic, will be to hit the disc on a hard surface but this will help free the heads of any blockage.

Cool the disc

An opposite solution will be to cool the disc instead of heating it. You need to place the disc in a bag which is generally used for frozen, put the disc in the freezer for a few hours.

You need to reconnect the drive to the computer and test if it works. If so, take the opportunity to dump the data to another drive as you will have fixed the issue in a timely manner and maybe the old drive will not last too long.
