Effective Methods for Secure Data Erasure and Information Protection

Data Erasure (also called data clearing or data wiping) is a software & hardware based method of overwriting data that completely destroys all electronic data residing on a hard disk drive or other digital media. Permanent data erasure goes beyond basic file deletion commands, which only remove direct pointers to data disk sectors and make data recovery possible with common software tools. Unlike degaussing and Secure Data Erasure which render the storage media unusable, data erasure removes all information while leaving the disk operable, preserving IT assets and the environment.
Simply deleting data from a hard drive does not mean that the data is gone forever. Considering that sensitive information falling into the wrong hands can lead to loss of business, property or reputation, or lead to civil and criminal liability, removing all traces of information stored on targeted media can be critical for data security.
