The price of computers are dropping every year due to advancements in technology. This has enabled more households to upgrade computing devices more often than ever before. All this combines to create an excess of old computers sitting idle and not being utilized. Disposing of an old computer may seem as simple as placing it in the garbage. A better alternative to putting the system in the garbage is having it recycled or donated. The Environmental Protection Agency provides tips for electronic recycling that can assist you in disposing of your computer responsibly, click the link for more information https://www.epa.gov/recycle/electronics-donation-and-recycling. Regardless of how you plan to dispose of the system, a data management plan is needed.

Due to the increase in personal data being commoditized by cybercriminals, it is highly recommended you remove your data from the computer prior to disposal. Getting rid of a computer with no thought given to removing data stored on the internal hard drive leaves you open to identify theft, bank fraud, online account compromise, etc.

For example, perhaps you have saved tax returns prepared six years ago or a file with online passwords stored on the system. If steps are not taken to remove this data from the old computer prior to disposal your data potentially becomes available to individuals that do not have your best interest in mind. Having a data management plan can alleviate this problem. Simply deleting files will not work. There is software available for free that can easily recover deleted files. To be sure your data is removed, wiping the system or resetting and reinstalling a clean version of the operating system is the best course of action.
If that old computer has data on it that you want to keep, do a complete data backup onto a portable hard drive prior to erasing or resetting the system in preparation for disposal. Once you initiate a system reset or data erase, retrieving your data is almost impossible. A good data backup is essential if you need to access information from a system you are disposing.

Your choice of disposal may determine your method of data removal.

  • If recycling the device, use a data wiping or secure erase method that renders the hard drive useless
  • If donating the device for reuse, use a device reset method recommended by the manufacturer of the device or its operating system software

Microsoft, Apple, and Google have streamlined the process for resetting a computer. Clearing a mobile device such as a smartphone or tablet is similar to resetting a computer. Included below are general steps to reset an iPhone, Android phone, Windows 10, Apple Mac, and Google Chromebook. Also, listed are links to free software for data wiping.

For digital cameras that seem to have been forgotten over the years. Remove any added memory card and delete all images from internal storage on the camera. If the option is available, reset the camera to factory default settings. Following these steps will reduce the likelihood of images being taken from the camera without your knowledge after you donate or recycle it.

The removed memory card should be reformatted after you save your data. Most computers have a slot to insert a memory card for reading data. Insert the memory and navigate to it from main computer file directory. Select the memory card and right click to format. The memory card should be formatted no less than five times to ensure data has been overwritten.

Remember if you don’t secure your data someone else will and that may have negative consequences for you and your family. Bookmark Alabama Cybersecurity to stay informed on the latest issues and useful tips to stay safe online.
