You have completed a forensic investigation case. you would like to destroy the data contained in various disks at the forensics lab due to sensitivity of the case. how would you permanently erase the data on the hard disk

1) The permanent method to destroy data from a hard disk would be to puncture the hard disk meaning to drill a hole into the disk.

2)Use software like Boot and nuke.

Explanation:

In order to increase the life span of hard drives the data that we store is distributed evenly over many sectors that are not adjacent. In traditional methods of erasing data such as formatting the disc the data can be reconstructed by using sophisticated tools available to various agencies, making our data vulnerable to reconstruction and use.

Physically damaging the hard disk renders the disk useless thus there is no way by which the data can be reconstructed.

Many safe and secure software are also avaliable like Boot and Nuke to destroy the data.
