A good IT professional knows that deleting a file doesn’t actually removes or destroys it from your hard drive. It actually deletes the index of the file in the File System which means only the access to the file is removed. Even when you empty your recycle bin or trash, the files aren’t destroyed.

Think of this as ‘when you delete a file, you actually hide them’. In a similar way, when you quick format a hard drive, it replaces the existing file system with the new but doesn’t destroy any file from the storage media. Therefore deleted, trashed, and files from a formatted drive can be easily recovered, unless overwritten, with the help of a data recovery software.

However, recovery isn’t always the requirement. Sometimes you need to destroy data beyond recovery in order to safeguard your privacy and confidential data. Therefore, before disposing off, selling, or throwing away your storage devices, it’s important that you securely erase and not simply delete sensitive files to make sure that there is no residual information left on the device that can be recovered with a standard off the shelf data recovery software.

Even if you don’t plan to discard your storage drive, keeping it sanitized and clean can help you prevent any unauthorized access to your data through malware.
