How to Permanently Erase Data So That It Cannot be Recovered
Today's tutorial will teach you how to erase data permanently so that it cannot be recovered. Many believe that having a file shredder on the computer means you are up to no good.
So when might you want to use a secure eraser? Lets say you scanned your drivers licence because a Government Department needs it to confirm your identity. It is obvious for something so confidential, you will need to use some form of encryption such as Pretty Good Privacy (PGP). However - you want to sell your computer to earn a few bucks. The issue? Your computer is covered in bank details, scanned copies of your drivers licence, birth certificate, etc.
The solution? Delete it from the recycle bin! One could wish it was that easy anyway. This article will explain how to erase that data so that it can never be recovered.
Run CCleaner -> options -> settings: Ensure "Add Run CCleaner option to recycle bin context menu is checked. Check "Secure File Deletion (Slower)" and change the overwrite to seven passes or a recommended 35 (Gutmann) pass. Further - check "Wipe Alternate Data Streams" and "Wipe Cluster Tips". See the image below.
Open Eraser -> settings: Ensure "default file eraser method" 35 passes and "default unused space erasure method" is 35 passes. Then click "save settings".
Feel free to also go to -> erase schedule -> task and you can have Eraser erase certain folders or even the recycle bin every day, week or month.
Now that we have installed the recommended software, and configured the settings for maximum results, we will now start the shredding process.
Step 1 Password Protect the document
First - go to the Ultra High Security Password Generator website and collect your password. I recommend the 63-random ASCII characters for ultimate protection.
Next - rename the document to "101010" as you don't want to keep the file name. Then right click the file, hover over Axcrypt then click encrypt. Enter the password but to paste it - press Ctrl + V. Press OK then the file will encrypt itself.
Step 2 Erase the document
Right click the document and press delete. It will then be sent to the recycle bin. Finally, right click the recycle bin and press "run CCleaner".
The document(s) is now impossible to recover and their is no need to worry about identity theft anymore. All the data is erased and unrecoverable. It is also impossible to find out what the file names were.
