There are many ways to remove the digital data from hard drives including very highly technical Secure Data Erasure but all they don’t give the real confidence to share highly sensitive storage media with anyone. If you are security adviser of a country and your laptop carry the border security plans than you can not take the risk to hand over that laptop to repair to anyone.
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.
Secure India can provide media disposal for you after the data erasure in an environmentally-friendly manner. When data storage devices have reached the end of their lifecycle, take advantage of Erasure Services to prevent your data from falling into the wrong hands.
