Data security is the practice of ensuring that the data are protected. Most people fail to secure the data in their hard disk as a result personal data become stolen. A stolen data can risk data breach, identity theft, and other crimes that suspects can run away with ease, rebuking you as the person responsible for the crime. This happens because people fail to eradicate data in their drive. Of course we know how to delete a file but what we didn’t know is what deleting a file completely means. What they perceived about file deletion is a big mistake. Hard drive shredding Montreal.
After the file is deleted and permanently removes(emptied trash) the index of the file is just forgotten, the file exists but resides in the free space, waiting to be overridden
Hard disk data destruction is the way to remove leftovers of the file.
The files that can be gathered are your credit card number, address, social security number and other personal information you willfully or mistakenly saved.
So how do we really delete files in hard disks?
If you are planning to sell or throw away the disk, you have to secure your data first. There are 3 methods for to destroy data securely:
Software data destruction
This method does not require to touch the disk to eliminate the data. It rewrites the data several times in alternating patterns.
There are 2 ways to wipe the data Selective File Wipe
Selective file wiping is a process where a user has control to what file has to be wiped.
A recommended solution for short-term use or if you are renting a computer in public places.
Boot and Nuke
This procedure erases all the files inside the drive. It is recommended when you are to sell the disk because it eliminates fragments of files without damaging the disk. The data destruction begins when the system boots up. It runs in the computer’s RAM which means all the data are entirely erased.
Permanently destroying the disk so that it becomes unreadable and unusable.It is best for damaged disks because it makes remnant files unrecoverable.
There are two ways to undergo physical destruction of disks: Using Tools.
Tools made for hitting, slicing, burning or boring holes found in our homes can make disks permanently unrecoverable. Open the hard disk using torx screw then destroy the platters. Just like that, you can be convinced that the data are gone for good.
Disk Destruction Services
Disk destruction services does the same job as what home tools can do only that it is using a machine specialized for the task. It is a very effective method and is it recommended by the Department of Defense for securely deleting data.
Also recommended by the Department of Defense, de-magnetism or degaussing is a hard drive data destruction method that removes the magnet in the disk Magnetism is required in a disk because it keeps the data intact even if the disk isn’t used for several years. When the magnetism of the drive is removed, the servo is also altered. Servo is the disk’s main chip, when data in the servo is gone, the disk will just be a worthless piece of junk.
Use data destruction when:
- I want to be secured when using computers public locations or locations I might risk data breach.
Use selective file wipe. Some file wiping software are portable, just install the software in your USB thumb drive and take it anywhere you go.
- I am planning to sell my old disk.
Format the disk first then use the Boot and Nuke method.
- I am planning to donate the disk.
Write the disk multiple times and use the Boot and Nuke method.
- I want to throw away my disk.
Use any physical destruction method or degauss it before throwing away the disk.
- Wiping disks using software are not as effective as physically destroying the disk. Overwrite the data several times to be sure. Only use data destruction services if the data is very risky to be exposed to the public or you have multiple disks to destroy. Data destruction services are as effective as manual destruction methods, but compared to doing it yourself, data destruction services are very expensive.
- If you want to destroy the disks yourself:
- Wear protective gears particularly when you are to use power tools.
- Aim at the platters, don’t stop until the platters have ripples or dents.
- Do not burn the disk as it emits toxic fumes.
- Do not put the disk inside the microwave.
Are there preventive methods?
The next time you buy a new drive, encrypt your hard disk. Data encryption makes the disk more safe from unauthorized data extraction by concealing the data so that it cannot be viewed by those that do not know the password. Data encryption software are attainable online for free.
When your disks have been stolen and your personal data gathered, you can risk identity thief. Identity thief is a crime, it takes away a person’s identity and use it to commit crimes. Do not become a victim of stolen hard disks. Keep yourself from encountering problems like data breach, or identity theft by securely removing data or encrypting the disk.
