How to Destroy Old Hard Drive Permanently?

Overview: If you do not need the old hard drive, professional hard drive shredding, physical destruction or approved magnetic degaussing are good options. But if you want to sell or reuse the old hard drive, using a secure SysTools hard drive erasure tool is the best option. To destroy old hard drive safely, first you have to take a backup of important files and decide whether you want to reuse the old hard drive or dispose of it permanently. In this guide, you will understand different methods for how to destroy old hard drive, compare common ways to destroy it, understand the safety steps and learn how to dispose of an old hard drive properly. .

Why Is Deleting or Formatting an Old Hard Drive Not Enough?

Deleting files or formatting an old hard drive does not always remove data permanently. The files may not appear on your hard drive but their data may still remain on the hard drive. Someone may be able to recover data by using data recovery tools. Here are some common reasons why deleting or formatting an old hard drive is not enough.

• Deleting the files

When you delete a file from an old hard drive, its data may remain on the drive until new data replaces it.

• Quick format

A quick format removes file records but may leave the old data on the hard drive.

• Data recovery

If data is still available on the hard drive, some tools may find or recover it.

• Privacy risk

Old files may contain personal photos, saved passwords, bank details or work documents that you do not want to share with others.

Reasons to Dispose Old Hard Drives

There are several benefits which you get while you try to destroy a hard drive. Let’s read those points below.

• It prevents unauthorized ways of recovering sensitive data.
• It complies with data privacy laws like GDPR and HIPAA.
• Also, protect your personal information which is stored in hard drives such as banking details and passwords.
• After you destroy your hard drive, it can also be used for recycling purposes to make the environment eco-friendly.

How to Destroy Old Hard Drive Using Manual Methods

Here, we will give you various destruction methods to dispose of your old hard drives. Follow these methods to securely protect your sensitive data.

1. Magnetic Destruction (Degaussing)

What it is: When a strong magnet or degausser is used to interfere with the magnetic fields. This is where the data is stored on the hard drive platters. A degausser creates a strong electromagnetic field that disrupts the data bits on the drive. How it works: After exposure to a degausser, the hard drive is completely rendered, unable to read, and can’t be operated. This destroys the platter alignment and you can’t boot or be recognized by any system. Why use it:

• Good for a fast kill on many drives.
• No need to take the drive apart.
• It is ideal for businesses with sensitive data such as in healthcare, defense, or finance.

Limitation

• Special requirements and the correct process required
• Hard drive become unusable after the process
• The result depend on the equipment, drive type and required data removal standards

#2. Physical Destruction

Know about this: Physical destruction is the physical submission of the hardware that involves disassembling and breaking of the internal components. Like it will break it down into pieces with a screwdriver, hammer, drill, etc. Steps to Function:

• Open the hard drive cover.
• Smash platters with a hammer or drill holes into them several times.
• Scrape or snap the mainboard to destroy the drive.

Need:

• It is cost-effective and doable at home.
• It provides peace of mind when you can see the damage.
• There is no need of any electricity or technical tools.

Tip: Wear gloves and glasses as the edges of the platters are sharp. If it struck, then they can shatter you. Limitations

• After physical destruction process you cannot re use hard drive anymore
• Injury can be happened with wrong handling
• Only damaging the outer parts of hard drive may leave the stored data untouched

#3. Shredding

Definition: Shredding requires an industrial shredder for electronics which is made specifically to damage electronics. It destroy old hard drive into tiny pieces that you cannot recompile or read. Ways to Do it: From the time it is fed into the shredder, the hard drive is ripped into tiny shreds by rotating metal teeth. The particles which are leftover are further discharged or recycled according to environmental laws. Why to use:

• It is one of the hardest ways to destroy.
• It is suitable for batch disposal in companies.
• Make sure that it’s in line with all the industry standards such as HIPAA, PCI-DSS, etc.

Limitations

• Need specialized equipment
• This method is not usually practically for home use
• The equipment and destruction process must the required standards to destroy hard drive properly

Note: To apply all this, you need expensive shredders which are usually only available in data centers or in recycling centers for waste electronics.

#4. Incineration

Overview: The hard drive is incinerated in an industrial burner at high temperatures. So, that it melts the components completely and can destroy them. Process Flow: The heat in fact, isn’t just melting the casing and the circuit board. But it’s causing the platters inside to warp or vaporize. After doing this,  it tends to eliminate all the remaining magnetic field for absolute zero possibility of data recovery. Reasons to Use:

• To wipe everything out from all the way to the bake lite, circuits, and platters.
• For secure or military/government data destruction.

Be Careful: Don’t burn hard drives at home because it emits toxic chemicals and needs controlled industrial environments with the right air filters. Limitation

• Incineration requires special industrial equipment and trained professionals
• This process can release harmful chemicals that it requires proper safety tools
• It is not suitable for home
• The cost of destroying an old hard drive this way may be higher than that of other methods.

#5. Crushing

Short Summary: Physical destruction crushes the drive to press the external case and internal platters to break it. This is accomplished through use of a hydraulic press or disintegrator to destroy old hard drive. Action Steps: The crusher exerts enough force to bend, break or destroy the drive. And once crushed, the platter inside can no longer spin up to store or read data anymore. Benefits:

• Speedy, not to mention less messy than taking it apart by hand.
• Can be used frequently which is applied by IT disposal companies.
• All the magnet teardown and leaves no doubt about the drive’s fate.

Limitation

• Special equipment is required
• The result depend up on the method use and how much damaged caused
• Crushing only outer parts but leave some data readable

#6. Data Sanitization

Introduction: Rather than physically destroying the images, data sanitization refers to utilizing software tools to write over the data in the images with random characters (multiple passes). This approach guarantees no possibility of data retrieval with any tool or software. How it Function: Instruments execute a number of passes (DoD 5220.22-M or NIST 800-88) to make sure data is securely erased. After this process, even the most sophisticated recovery methods available are not able to get the files back. Purpose:

• It’s Eco friendly like you can reuse the drive.
• Very affordable and suitable for individual use.
• It complies with industry security standards.

Limitation

• The process may take time and it depend up on hard drive size
• It may not work on damaged and unreadable drive

How Does a Hard Drive Store Information & Its Types

Basically, hard drives store the information in various forms including images, videos, music, and data which contain things like social security numbers, banking details, and passwords and etc.

• Computer programs: Software that helps your computer run and store data.
• Operating systems: Software that manages your computer’s resources.
• Internet history: Data from websites visited, cookies, and other stored info.
• Software applications: Programs like word processors or games.
• Databases: You can search collections of information.
• Media files: Images, videos, music, and other media on your computer.
• Email: Messages, attachments, and contacts stored on your computer.
• Documents: Files like text documents, spreadsheets, and PDFs.
• System files: Settings, configurations, and logs for your system.
