Summary
In Mac OS: Select the Disk Utility from Applications and Utilities. Select the drive from the left menu. Select Erase from the top menu. When you format a hard drive you don't actually erase the hard drive of data, you only erase the location information for the data, making it 'lost' to the operating system. Since the operating system can't see the data, the drive looks empty when you look at its contents. Formatting a hard drive does not completely erase data either. Though operating system cannot see deleted or formatted data and the drive looks empty, average users are able to get back lost data easily with the help of hard drive recovery software. A full format may protect the data from basic data recovery attempts but specialized data recovery software and services can get back ‘traces' of data from a fully formatted drive. Thus, you need to use a software that can erase data as per international data erasure standards such as DoD 5220.22-M. To permanently destroy data from Windows.
