Summary: Many people believe that erasing, shredding, wiping, and deleting the data means the same thing. But the reality is these terms are as different as chalk and cheese. This blog clearly explains these simple terms that are often used synonymously and interchangeably. This will help you choose the appropriate process to get rid of your sensitive data and ensure that it is safe.

Whenever we hear the terms, like wiping, shredding, deleting, and erasing, we often think these terms are used interchangeably. However, this is not the case. These terms might be synonyms for a layman, but an expert knows that they are not. Each of these terms denotes different meanings with different outcomes. In this blog, we will discuss the differences between these terms and their specific uses.

1. Delete

Most of us believe that deleting a file removes it permanently from the storage device. However, this is not true. Deleting a file or folder removes it from the location where it was originally saved and moves it to the Recycle Bin. Even if you use the Shift + Delete combination, it only helps you skip the sending of data to Recycle Bin and directly makes it inaccessible. Such data still remains on your storage device and can be easily recovered using a data recovery software.

2. Erase

Erasing is the process of removing data completely from the storage device without any chances of recovery. In technical terms, the erasure process overwrites the data with binaries or other redundant data. The original data is buried and distorted in such a manner that it becomes impossible for any recovery software to identify and recover it. There are various data erasure tools available in the market that help in erasing data in accordance with the international data erasure standards.

3. Shred

Shredding is similar to erasing the data but on a smaller scale. If you want to erase selective data and not the complete drive, this process allows you to select particular files and erase them. Shredding process involves erasing the selected files by overwriting them with random patterns or 0’s and 1’s. This way the deleted files become impossible to recover even using a data recovery software. Most of the quality data eraser software come with an option to select specific files and shred only them without affecting other data.

4. Wipe

Wiping is another form of erasing process. However, it is applicable when you need to completely erase all the data on a storage drive. Wiping a storage device not only permanently erases the existing data but also overwrites any past deleted data that may be still lying idle on your drive.
