We often find out that some info is no longer to need on our hard drive. Additionally, when we sell our old computer or give it to others, we are not willing to let some things on our hard drive be known by others, such as our bank account details. To ensure the safety of our data, generally speaking, we delete our files from our computer and thought it was erased and no one else will see it again. In fact, it can’t be erased completely by deleting files. Because it actually gets hidden and is still in our hard drive, others can see our data if he wants. To erase our hard drive completely, what should we do?
On the one hand, we can overwrite our hard drive. How to overwrite our hard drive? If we have a Mac, we can overwrite them by choosing “secure erase trash” from the “file” menu. These programs work by overwriting your deleted files several times with meaningless data to ensure that they are completely erased. It is easy and safe.

Overwriting files

If we have another computer, we can overwrite the deleted file by special software, for example, Eraser, KillDisk and Mutilate File Wiper.
ON the other hand, we can clean our hard drive by reformatting it and re-installing our operating system. But this is difficult. We should do it when we are confident or let it do by someone else who is good at this. Pay attention to that, formatting our hard drive using the “Format” command may not erase the data completely.
Finally, if we still worry about that our data on our hard drive may fall into the wrong hands. There is an extreme solution. We can destroy our hard drive. After taking out the hard drive from computer, burn it or drill some holes in it so that nobody can use it again.
