There are many utilities that can help PC users to recover files that they thought had been permanently deleted. Some popular options include Recuva, Data Recovery Pro, and Disk Drill. For example, Recuva works by scanning the hard drive for deleted files and attempting to recover their data. It does this by looking for the file’s data in the space that was marked as available for use by the operating system, and if it is able to find the data, it can restore the file. Other utilities work using a similar principle of scanning the hard drive. It is important to note that the chances of successful recovery can vary depending on the age and condition of the hard drive, as well as how long ago the files were deleted. It is always a good idea to create regular backups of the important files to prevent data loss in the future.
In high-security environments, it is often necessary to permanently wipe data from storage devices to prevent sensitive information from falling into the wrong hands. Some utilities that are commonly used for this purpose include DBAN (Darik’s Boot and Nuke), Eraser, and SDelete. These utilities can securely erase the data on a storage device, making it extremely difficult or impossible to recover the deleted information. They usually work by overwriting the data on a storage device multiple times with random patterns of bits. This effectively destroys the original data and makes it impossible to recover. This process is sometimes known as “data sanitization” or “data erasure.” It should be mentioned that using these utilities can permanently destroy the data on the storage device, so it is important to use them with caution and only when absolutely necessary.
