Data is undoubtedly important to us. And, accidentally losing your crucial files, be it your official documents, project presentations, personal photos, or videos, could land you in serious trouble. Luckily, there are quick and effective data recovery methods to recover your lost files in seconds. But, when you want to do just the opposite and purposely want to get rid of some confidential or unwanted data, you try to find out how to delete it permanently.

When it's about deleting data, you may opt for dumping the files into Recycle Bin, use the Shift + Del key, empty the recycle bin, or entirely format the hard drive. Attempting all these methods will surely delete the data, but deleting data doesn't make it unrecoverable. It only makes the data' inaccessible.' How? Let's understand.

How Data Deletion Process Works

Each file or folder on your hard drive contains a 'pointer,' which lets the OS (Operating System) know where the file starts and ends. It also keeps track of a file being accessed. When you permanently delete a file, the pointer gets removed, but the file remains there, though inaccessible. It is because the OS makes the space consumed by deleted file available for storing new data. If you add new data in that space, the deleted data will be overwritten. But if you stop using the hard drive immediately after deleting the file, you can recover the inaccessible data with the help of a data recovery software.

What if I destroy the entire device?

Don't think of simply destroying the device. Some of you may be like – okay, I don't need the data, and drive is also getting old, it's better to destroy the device, so l won’t have to worry about my data at all. Again, don't do that! Throwing away your device or physically destroying it will not help wipe data. It may become an even bigger problem for you, if not treated carefully. Moreover, keep in mind that discarding IT devices irresponsibly also causes serious damage to the environment.

Additionally, you're putting your data at risk by destroying the device. Several technically sound data recovery experts can restore data even from partially burnt, water-damaged, or physically broken hard drives.

If you genuinely intend to get rid of your confidential/unwanted data, just deleting it isn't going to weed it out. You have to 'erase' the data indeed.

What Does Data Erasure Mean?

Erasing data or data erasure means permanently wiping it from all storage drives, such as HDDs, SSDs, Windows systems, USB drives, and more. The purpose of data erasure is to overwrite data on every sector of the hard drive with ones and zeros or some random patterns to make sure nobody gets access to it.

How to Erase Data beyond recovery scope?

To ensure that the data is completely wiped, use a powerful yet easy-to-use file erasure software, such as BitRaser File Eraser. It is a DIY (do-it-yourself) software that can efficiently erase Word documents, Excel files, photos, videos, audio files, etc., from PCs/laptops and external storage drives, such as HDDs, SSDs, or USB drives.
