Why no standardised erasing patterns, to ensure truer Data Sanitization: Also, compromised networks and laptop theft and loss, as well as that of other portable media, are increasingly common sources of data breaches. I do think BB is a great solution for Linux, but how can I trust a functin that just says overwrite with no explanation of what is meant by this term, from a technical stance. Permanent data erasure goes beyond basic file deletion commands, which only remove direct pointers to the data disk sectors and make the data recovery possible with common software tools.

Theft of an SED results in a physical asset loss, but the stored data is inaccessible without the decryption key that is not stored on a SED, assuming there are no effective attacks against AES or its implementation in the drive hardware. Purge file, “wipe” unallocated disk space and swap temp file space on affected systems. E-waste presents a potential security threat to individuals and exporting countries.

Find where contaminating information is written. WinPE has now overtaken Linux as the environment of choice since drivers can be added with little effort. Department of Computer Science, University of Auckland. Data erasure sometimes referred to as data clearing or data wiping is a software-based method of overwriting the data that aims to completely destroy all electronic data residing on a hard disk drive or other digital media by using zeros and ones to overwrite data onto all sectors of the device.


Make certain that the entire recording surface is completely removed before disposal. Data erasure can be deployed over a network to target multiple PCs rather than having to erase each one sequentially. While there are many overwriting programs, only those capable of complete data erasure offer full security by destroying the data on all areas of a hard drive. From Wikipedia, the free encyclopedia.
