It is important to wipe data from a computer’s hard drive before selling, transferring ownership, or disposing of it as simply deleting files does not erase the data completely. When files are deleted, only the file name is marked as deleted, and the data remains on the disc sectors until overwritten by new data. This can allow someone to reassemble the file if they desired the data. File wiping is a necessary security measure to protect personal and sensitive information.
The Importance of Data Wiping: Keeping Your Computer Safe
What is Data Wiping?
Data wiping is a safety measure that ensures that all data on the hard drive of a computer is fully erased. This is important when transferring ownership of a computer, retiring a computer, or even when purchasing a used computer. With data wiping, all personal information and sensitive data are eliminated, so the next person who uses the computer won’t be able to retrieve any of your past data.
Not Erasing After Deleting
Most people believe that simply deleting files or applications from their computer is enough to erase that information permanently. However, this is not the case. When you delete a file, only the file name in the directory is marked as deleted. The data remains on the disc sectors and can be retrieved using specialised software. This means that someone could potentially recover your deleted data, which is a major security risk.
