How to Physically Destroy a Hard Drive?
Anything that damages the platter comes under physically destroying the drive.
This way is a bit tough method.
If you do not intend to use that drive again, then the best way is to destroy it physically.
- The platter consists of aluminum plates with a magnetic plate.
- You can also crush it to destroy the data on it.
- A sledgehammer would be enough for this task, but if you want, you can use other objects too.
Hard Drive Destruction:
On an HDD, the data is stored magnetically. So they can be destroyed by the following methods.
These methods are described briefly here. They will be explained ahead in the article too.
This degaussing refers to changing the magnetism.
You can use a degausser.
This method will disrupt the magnetic domains on your drive.
One more thing that you should be aware of is that on degaussing a drive, its firmware will also get affected.
In this way, it will be completely useless.
2) Heating the Drive:
This heating means melting, which changes the magnetism.
Hammering on it makes it difficult to read the data.
When the metal deforms, it becomes more challenging to determine which sectors contain the data.
You can get an individual drill or a proper homeowner tool kit with all tools.
- This drilling removes the sectors altogether.
- It removes the layout physically, just like hammering.
- It also generates heat.
It is better than hammering.
6) Chemical Corrosion:
This method includes removing the magnetic substrate from the platter, so nothing is left to recover.
This leaves only the metal scarps thus nothing to recover.
Some other methods include:
How to Destroy a Hard Drive With Water?
Well, the hard drives that have got wet are not supposed to be eradicated.
Water alone cannot harm them.
The data is stored on the disk magnetically.
Thus by water, the data is recoverable. Water alone is not enough.
So you can get this work done by using chemicals solutions.
A) Sodium Bicarbonate Solution:
You can also use sodium bicarbonate, an electrolyte to destroy it.
B) Hydrofluoric Acid:
Hydrofluoric acid can help you try it.
But it is a bit dangerous to handle it.
Hydrofluoric acid is a contact poison. Exposure to it can cause a heart attack and even death too.
So I advise you not to use it.
How to Destroy a Hard Drive at Home?
One of the easiest ways of destroying is by heating it over a high temperature (above 1100 centigrade) and then cooling it below 900 centigrade.
This will first reset the material’s magnetic field, and it will cause an antiferromagnetic effect which will make the data written on it irretrievable.
This happens because the cobalt oxidized to Co3O4 then on cooling it loses the oxygen atom and becomes CoO.
Well, heating sometimes alone is not enough to destroy it.
You can achieve this by transforming your platter into piles of molten liquid.
For this you can use :
A) A Standby Fire.
It will undoubtedly liquify your hard drive.
B) A Blowtorch.
Get a protective gear then hold the platters at a distance. You can use a heat-resistant tool to do this. you will see it melting
C) Utilize the Thermite:
- Fill a large container with sand.
- Place the platter on this bucket of sand
- then light a container with thermite over the platters.
Be careful while doing this and don’t use it indoors, near children, in the forest and near yourself too.
D) By Microwave:
- Buy an old microwave.
- Put the drive in it and then heat it for 1-3 minutes.
- Then get far away from this place ad the glass platters can shatter too.
- Open the microwave with the help of a broom.
How to Destroy a Computer Hard Drive?
- To do this first, you need to locate the position of the hard drive on your computer.
- Then remove the screws using a screwdriver.
- Sometimes screws are hidden underneath, so you need to open them too.
- Remove the drive from the computer
- Then strike it on the various side so that it gets open
- After it is opened, maneuver out the round platter disk from inside.
- This round platter is silver in color.
- Then scratch this platter.
- You can also cut it up to destroy it.
How to Destroy a Laptop Hard Drive?
Before moving ahead, you need to know how it works and records data.
It uses a system of binary numbers, i.e., 0 and 1 to record data.
This data is stored in blocks on a platter.
The inner platter can be made from different materials.
Some such materials include:
Well, you can use a sharp magnet to do this task.
1) Take a Backup of Your Data:
Well if you have your favorite songs and some family pictures stored in it, then you will surely need them again.
So make a backup if it contains your essential data,
2) Wipe the Drive:
Before destroying it, you need to clean the whole data from the drive.
Well, the data after destruction is irretrievable, but that’s not 100percent correct every time.
3) Open the Case:
Open the case and locate the hard disk drive.
The position at which they are located might differ from case to case.
If you are having any difficulty in searching for it, then search for that model from your manufacturer’s site.
Open the drive:
4) Smash the Drive:
Take out the platter and smash it with a hammer.
Then collect the pieces and dispose of them.
How to Destroy a Hard Drive Without Removing it?
Software-based shredders can do this task for you.
One of the easiest and the most common method includes deleting the data on it and then replacing it with any arbitrary characters.
How to Completely Wipe a Hard Drive?
Wiping means removing its content permanently.
On formatting a drive or deleting its partitions, what you are doing is only removing the file system and making the data invisible to users, and that data is not entirely gone.

To make sure that all data is entirely removed, you need to wipe it using some special software
The time is taken to complete this process can be from several minutes to some hours.
It all depends on the size of the data and the software that you are using.
Hard Drive Wipe Tool:
Data destruction software is also termed as:
- Data sanitization software
- Hard drive eraser software
- Disk wipe software
On deleting files and emptying the recycle bin, you think that that the data is deleted.
But in reality, it isn’t.
You just deleted the reference to that data, so OS cant finds it.
The data is still there and can be recovered with some tools.

- Secret safe
- Laser oscilloscope
- Wind chimes
- Tesla turbine
- Mic stand
- Cotton candy machine
- Cell phone charger
Many people don’t know what to do with old hard drives.
Many computer and laptop users have zero knowledge in this regard.
They never realize that they have a lot of sensitive data on such a drive.
Their risk is exponentially more significant than the business level. The files on it might contain your bank account information or some other vital data of this sort.
