5 Tools to Permanently Erase Files and Prevent Data Recovery

Summary: In this blog, we’re discussing the best five tools that will help you permanently erase files and prevent data recovery. You can review these tools based upon their features, ease-of-accessibility, data erasure results, etc., and choose the best one as per your needs.

In today’s digitally empowered world, safeguarding privacy and confidential data from unauthorized access is a bit difficult especially when the user lacks knowledge about the importance of data sanitization before discarding, selling, or donating devices with memory (storage).

To protect data, generally, users encrypt files & folders, hard drives, password protect flash drives and encrypt SD card on their smartphone to avoid unauthorized access to their confidential data. Use of antivirus & anti-malware tools is another way of safeguarding the privacy. But almost all of these devices (hard drives, SD cards, smartphones, laptops, etc.) are discarded, sold, or donated without proper data sanitization at the end of their life cycle.

Deleted data can be easily recovered from any storage media whether it’s a USB thumb drive, HDD, SSD, SD card, etc. Interestingly, data from a formatted, encrypted, and broken or crushed storage media can also be recovered using a data recovery software and services. Therefore, to protect and safeguard your confidential data from an unauthorized access, you must erase the files/folders and wipe the empty spaces (unused space) on your hard drive volume as the empty spaces might contain previously deleted sensitive and private data that can be easily recovered.

Tools to Destroy Data Permanently – Beyond Recovery

There are several tools out there in the market that you may choose but most of them aren’t capable of data sanitization and are also complex to use such as SDelete, WinHex, etc. Therefore, to save you from the trial and error, we worked on choosing the 5 best tools available in the market to permanently erase files and folders beyond the scope of recovery.


Eraser is a security tool for Windows that erases data from storage drives by shredding and overwriting it several times with selected patterns. The tool is helpful in maintaining the privacy and also allows users to remove selected files instead of wiping the whole drive.

The tool also provides an option to schedule eraser of specific files on the system based on date and time. The software uses the following algorithms to erase data from a storage media:

  • Write Zero
  • Gutmann
  • Random Data
  • DoD 5220.22-M
  • HMG IS5
  • GOST R 50739-95


  • Doesn’t have a user-friendly interface
  • Doesn’t verify destroyed data
BitRaser File Eraser

BitRaser for File is one of the most powerful data erasure tool available online. The tool is developed by Stellar Data Recovery—a renowned organization known for its data recovery, data migration, and data erasure solutions. Therefore, the BitRaser File Eraser is much more reliable and secure than the above-listed data eraser tools.
