How to erase data completely from your hard disk

How to erase data completely from your hard disk

We can understand the importance of data recovery; after all it is about recovering our lost data which are important and crucial. But what can be the merit in erasing data from hard disk? We had spent a lot of time in storing it in the computer! Well, to get answer to this question, consider the following scenarios:

You are thinking of buying a brand new computer, because you are bored with the old one, but as the old one is in working condition, you want to either sell it or donate it.

Your hard disk has become corrupted somehow, so you want to clean it in order to reinstall the operating system on it.

Your hard disk is physically damaged, so you are thinking of disposing it.

In order to prevent identity theft, you are deleting financial and personal information 'on the go', so that it cannot be retrieved by crackers and identity theft malware.

You have ex clients, patients or customers who do not want their confidential data to be on your computer any longer.

The main point in all the scenarios given above is to remove data from your hard disk and in a way that it should be impossible to retrieve it so that no one with a malicious intention can access it.

Many people do not care about the importance of erasing data completely. They think that if they delete item by pressing shift + delete button on their computer, it will get deleted permanently from their system.

Well, this is not the case. Delete or Shift + delete function in an operating system merely hides the presence of an item on the computer. The item remains on the hard disk with a new name as long as the space acquired by it is not needed by the operating system for reuse. Even then, you can not guarantee that the data is gone forever because efficient data recovery software will retrieve this data very easily.

So if you are serious about inaccessibility of your erased data, you will need something more than Delete or Shift + delete function. Select an efficient data erasing tool to ensure complete removal of data from your hard disk. Only a data erasing software of standard can guarantee that the data is erased beyond recovery. There are tools that can give you selective erasing of data; that is you can delete selected such as individual files or documents from your hard disk drive.
