How to protect your laptop data before you exchange it

Risks of Not Protecting Data

Here are some profound risks of leaving data unprotected:

• The data stolen from you can be used to impersonate you, and fraudulent activities can be performed under your name.

   

• If your bank or card details are recovered, they can be used for financial crimes. 

   

• When your login details are available, your emails and social media accounts can be hacked. 

   

• Unprotected corporate data, like client information, can be leaked.

   

Backup Your Files Before Selling

Your laptop may contain years of data, with multiple photos, documents, browser tabs, etc. It may therefore be essential to back up data before selling a laptop or exchanging it. One of the backup methods is using a hard drive for physical backup. An alternative is backing up files on cloud services like Google Drive and OneDrive. 

You can also use full-disk backup programs like ‘Macrium Reflect’ and ‘Acronis True Image’, which enable the user to save complete systems.

Securely Erase Data from Laptop

MacBook has an ‘Erase All Content and Settings’ tool that can help with complete erasure that a factory reset may not be able to perform. On a Windows laptop, this step can be taken by going to the System Settings, then going to the Recovery menu. If you have a Chromebook, since they have cloud-first storage, complete erasure is relatively easier.

Factory reset

To factory reset your Windows laptop before you sell it, start by backing up your data. Then go to your device’s System Settings, then to ‘Recovery’ and click on ‘Reset this PC.’ You can then choose the ‘Remove everything’ option and enable ‘Clean data’. For a thorough reset, choose the ‘Cloud download’ option. Then follow the prompts to reinstall Windows. 

To factory reset a Mac, you can choose to use the ‘Erase All Content and Settings’ feature by going to the System Settings, then selecting ‘General,’ ‘Transfer or Reset’, and then finally clicking on ‘Erase All Content and Settings’.

Data erasing software

One of the things to do before selling a laptop is data erasure. Data erasure software takes security to the next level by permanently deleting files and data from digital storage devices. Unauthorised users cannot recover this data. Popular programs created for this purpose are DBAN and BitRecover Disk Wipe. They operate by overwriting your hard drive repeatedly, which makes recovery impossible.

Remove Linked Accounts and Licenses

One of the data protection steps before laptop resale is to sign out of your Google, Microsoft, iCloud, and other accounts. Sign out of all browsers as well. Certain app licences are connected to a specific device, and their deauthorization is essential for later reinstallation. Unlink your laptop from services that track your device, like Google’s Device Manager.

Final Checklist Before Handing Over Laptop

• Make sure that all data on your laptop is backed up. 

   

• Sign out of all accounts.

   

• If you have licences for software, deactivate them before handing the device over.

   

• Perform a secure factory reset. 

   

• Delete sensitive files manually.

   

Conclusion

Erasure of data through secure means is crucial if you want to prevent identity theft and fraud. Keep essential data backed up, perform a factory reset, sign out of all accounts, and most importantly, use data erasing software. Follow the right steps and enjoy the transition to a new laptop.
