• How to: wipe your computer of data

    Date:14 November 2019 Author: Leila Stein

    If you’ve recently got a new computer or are planning to move onto a new machine, it’s important to know how to effectively wipe your old laptop of your personal information before selling, donating or recycling it. Here is how to make sure you’re not handing over intimate details:

    Back it up

    Before wiping clean, make sure you have everything you want from the computer first.

    Either back-up all your important information to an external hard drive, your new computer or a web service like Dropbox, Google Chrome or iCloud.

    It is likely that you’ve been doing this regularly anyways, as many laptops already backup to a cloud service. Backing up to the cloud is your best option as there is always the possibility that hard drives could crash.

    Keep your passwords and keychains

    If you don’t want to go through multiple “forgotten passwords” processes, it’s important to either write down or save your passwords to a third-party password application such as Last Pass.

    If you have any software you will need to re-install on your new computer, keep the keychains as these will be removed once you do the factory reset.
