How to Completely Erase Hard Disk Data You need to use a degausser if your intention is to completely erase the data on your hard disk. You may be used to deleting data on your hard drive or other storage device using your PC. Deleting data this way does not actually completely delete it, but only moves it to an inaccessible part of the hard drive. This explains why it is possible to recover data from a formatted hard drive. However, using a degausser will completely wipe data in the hard drive. The data on a hard drive that has been degaussed is randomized and cannot be recovered. The average consumer usually has weak data protection practices. In some cases, you will find people selling their hard drives without wiping them clean. If the hard drive falls into the hands of a person with malicious intentions, your data can be recovered and used. This is why simply formatting a hard drive prior to selling it is not enough. It is crucial to ensure the data on the drive will not be recoverable. Degaussing is the best way of making your data irrecoverable. Before you sell your computer, you should degausse your data. Wiping the hard drive cleans is also important for businesses that want to replace their aging computers with new ones. You do not want your confidential business operations data falling on the wrong hands. Government institutions also usually have sensitive data. Degaussing should be a primary requirement for government departments. Generally, anyone who is concerned about their data landing in the wrong hands will benefit from degaussing.
A 10-Point Plan for Computers (Without Being Overwhelmed)
Overview of How Degaussing Works Magnetism is the primary way through which degaussing erases data from a hard disk. Most hard drives have a magnetic strip inside where data is stored. When the drives are inserted into a computer, the data on the strip is converted to digital format. The digital format of the data is what appears on the computer screen as different types of files.
The Essentials of Data – Breaking Down the Basics
Degaussers use magnetisms to erase data on the hard disk. When a degausser is powered, it produces a strong magnetic field. When a storage device is introduced into this magnetic field, the data magnetic strip is damaged. The data cannot be recovered from the hard drive that has been put into the magnetic field since it has been randomized. This is why it is impossible to retrieve data from a hard drive that has been degaussed. There are different types of degaussers in the market. Electromagnetic degaussers are among the most common types. The above is a summary of how degaussers work to erase data from storage devices.
