How To Securely Dispose of Old Phones and PC’s and Laptops

When PCs, laptops, phones, and other devices need to be replaced, disposing of them in a way that does not pose a data security risk is especially important. Here are some tips on how to dispose of devices securely.


Before beginning the disposal process of your device, the first thing to do is to make sure that you have a backup of all your important files and data.

Backing Up Your PC

To back up your PC, you could use:

– An external hard drive e.g. Maxtor M3, WD MyBook Duo, Toshiba’s Canvio, LaCie Porsche Design. Many other options are, of course, available. If you have a Mac, make sure your chosen external hard drive is Mac compatible.

– A cloud-based backup service, such as Dropbox, Google Drive or Box. These have large amounts of free storage plus, or for a relatively small fee, you can buy more storage space if needed. For example, Box gives you 10GB of file storage for free, Google Drive gives you 15GB of storage for free, OneDrive gives you 5GB of free storage space, and Apple iCloud gives you 5GB free.

Transfer Files To A New Computer

If you are thinking of purchasing a new or refurbished computer, we can assist you in transferring the files from the old straight to the new, although having an up to date cloud backup of your work and critical files is good practice anyway.

Sign Out Of Online Accounts

With everything backed up safely, the next step is to make sure that you know login details for (and have signed out of) any online accounts on the old computer. For example, these services/apps could include Facebook, Twitter, Google, Apple and Microsoft.

Wipe The Hard Drive

The next step is to wipe all traces of your data and activity from the hard drive. For those who are planning to wipe the hard drive of a computer that belongs to your employer/the company you work for you will need to first check what the company’s recommended policy or procedure is for doing so, and to check that your actions will be compliant with data protection laws e.g. GDPR.

The procedure for wiping data from the hard drive can vary for the operating system (version of Windows or MAC OS). It also depends on which type of hard drive you have, whether the traditional type of drive, various types of SSD or indeed storage drives built into the main board of the computer itself. This is common with certain Macs and smaller laptops.

If you want to preserve the operating system after wiping the data then there are various 3rd party applications that can do this such as File Shredder, Eraser or WipeFile. If you have an older Mac with a hard drive move your files to the trash can and use Secure Empty (Trash option Finder > Secure Empty Trash)

A safer way would, however, be to run suitable data erasure applications and then reinstall the operating system from scratch.

Before doing this, you may need to deauthorise the computer with relevant accounts. For example, some SaaS accounts (Microsoft 365) and entertainment accounts such as iTunes only allow you to use a certain number of authorised, named devices. If you are getting rid of your device you will need to de-authorise this device with those accounts, thereby enabling you to authorise another device/a new for use in its place with those accounts.

If you are not wiping the whole drive, you should delete browser data. Since browsers save information about your browsing history and can store usernames, passwords, and other sensitive personal data, delete your browser history and make sure that you are signed out of your browsers. For example, to clear your history in Microsoft Edge, go to the three dots (top right) open the browser menu and go to Settings > Privacy & security and select “choose what to clear”, making sure that all checkboxes are selected so everything gets removed. The same will need to be done for all other browsers e.g. Chrome, Firefox, and Safari.

You should also uninstall programs, Some programs contain personal data and, therefore, need to be uninstalled.

– Macs (macOS) restart, coupled with Option+Command+R. The process for of wiping the hard drive for Macs is to erase and reinstall the operating system. To do this, go to Apple menu > Restart and, just as it reboots, hold down Option+Command+R until the spinning globe appears. Then, release the keys, choose Reinstall macOS, choose Continue, and follow the instructions.

– Windows PC reset. For a Windows PC, go to Settings (app), click on Update & Security, click on Recovery, choose Get started under the Reset this PC option, and remove all personal files during the process.

– Chromebook factory reset. To wipe your Chromebook, sign in to the Chromebook with the owner account, from the taskbar, click on Settings > Advanced > Powerwash > Restart. When the Chromebook restarts, select Powerwash and click on Continue.

Destroy The Hard Drive

If the computer itself is not working, you may not be able to carry out any of the steps above. In this case, if you need the data to be recovered, we can assist you. Alternatively, you may want to remove or destroy the hard drive first of all before recycling the rest of the equipment.

In any case, some experts recommend destroying the hard drive in order to be absolutely sure that any sensitive data stored on it cannot be recovered. This can be achieved by removing the hard drive and drilling holes in it or hitting it with a hammer until it rattles in the case of laptop hard drives.

To remove the hard drive, disconnect the PC from its power source, open the casing and locate the hard drive (generally connected to a SATA data and power cable). Remove the hard drive from its cage by undoing any screws.

If the device is on the premises of your business at the time, you will need to ensure that care is taken in order to comply with health and safety regulations if trying to physically destroy the hard drive.


As with a PC, make sure all important files are backed up, accounts are signed-out of, de-authorisation is completed, and browser data is removed. With laptops, use software to erase the data e.g. File Shredder or Eraser, and remove the hard drive, while taking care to avoid any damage to the inside of the laptop. We can assist with this if you are nervous about undertaking this yourself.


After backing up your important files and data, the best method for preparing to dispose of a tablet in a way that maintains data security is to use a full factory reset.

This varies depending on the make and model of tablet, refer to your manual or manufacturers website for guidelines. Alternatively, you can contact us for information on our in-house services.


Phones contain vast amounts of personal data and potentially sensitive company data. It is, therefore, extremely important to dispose of them in a way that does not compromise your security and privacy, or the security and privacy of your business/your employer, or any stakeholders and contacts.

As with tablets, this varies depending on the make and model of the tablet. Refer to your manual or manufacturers website for guidelines. Alternatively, you can contact us for information on our in-house services.


Firstly, ensure that you have backed up your phone contacts. After backing up your important data the process is:

For Android

Most up-to-date android phones have a microSD card where the phone’s data is stored. Remove the back of the phone, remove the battery, and remove the microSD card. This can be used in your replacement phone. You will also need to remove your SIM card.

If you need to wipe a microSD card, you can attach it to a laptop (with a USB cable), open ‘My Computer’, locate the microSD card, select all files stored on it and click delete.

After this, you can perform a factory reset to erase anything else left on the phone itself.

For iPhones

An iPhone has an in-built way to return it to its factory default settings, thereby removing your personal data. To do this, go to General, Settings, Reset, and Erase All Content and Settings. This will require you to enter your username and password, and you will be given the chance to update your iCloud backup before you go ahead with the erasing as part of this process.

Data Wiping Company

Another option is to simply use a trusted third-party data wiping company. Contact us first about our data wiping, certification and recycling services.


After you have wiped your device, and depending on whether the device belongs to you or the business/organisation/your employer, your options may be to recycle, sell or donate the device. In any case, if the hard drive has been removed, you will need to inform the person, or organisation that you are selling or donating the device to.
