Hard Drive Destruction
In fact, the only reliable way to destroy a computer file is to Physically Destroy every hard drive where the file has been stored. Physically Destroying gives you in-house control of all sensitive and private information. Computers have been designed to be resilient. They allow information to be recovered if accidentally deleted or even if the hard drive has been reformatted. Even after deleting or reformatting the hard drive, magnetic patterns of existing data still exists on the disk platters. Physically Destroying demagnetizes the entire hard drive including the disk platters – leaving no magnetic patterns on the hard drive.
