Data destruction is a term that refers back to the removal or eradication of magnetic or optical computer storage media. The process of destruction varies, based mostly on the medium and method used in the procedure. The purpose of data destruction is always to physically destroy the data so as to take away the chance of recovery.
more info here - ATI Secure Docs - Computer storage media requires some kind of sanitization at the conclusion of it's working life, specially when it holds sensitive information that may inadvertently be read by others. This really is extremely relevant to businesses and corporations, where data might have information regarding everyone or third parties, such as clients. Similarly, confidential corporate information, including patent designs, business strategies as well as other sensitive data could be accessed by third parties in the event the information is not removed.
Like i said previously at the outset, methods of destruction vary, based upon storage medium. For each and every storage medium, a number of destruction techniques also exist.
ATI Secure Docs - Optical media, for example cd roms, DVDs could be destroyed by granulating the plastics into 5mm chips. This technique doesn't take away the data, but makes recovery near impossible. However, removing the thin film that coats the most notable side of the disk, by scraping, scouring or sanding will physically destroy the data. In comparison, using microwave ovens, a less conventional technique, is extremely effective as a result of static charge and consequent arcing across the thin film storage layer with the disk.
Typical modern magnetic media constitutes tape backup units and difficult Disk drives. Unfortunately, tape backup units are very difficult to destroy, due to the entire tape, where a movie of iron oxide layer retains the magnetic media. Shredding of these media is achievable, but requires significant expense in plant capable of handling such devices. Acids, particularly, Nitric acid, at 50% concentration, will react violently with the iron oxide layer, destroying it completely in a few minutes. However, this process necessitates the removal of the outer plastic case to adequately expose the internal media storage tape. In certain circumstances, incineration of the storage media could be an alternative. However, this may inadvertently expose the operator to carenogens and may even be prohibited in certain countries.
get info - ATI Secure Docs - All of the Computer drives available, way of connectivity (SATA, IDA, ATA, SCA, SCSI) means that data destruction software has already established being intelligent enough to tell apart between these different interfaces. Software driven destruction of hard drives can be a highly efficient eradication technique that has been shrouded in urban myths, masking the actual ease in which data can be permanently removed. In many instances, an individual pass binary wipe (writing random zeros and ones to the drive) will permanently remove all data from your memory. However, international standards exist, which all require more significant wiping processes, a few of which will inadvertently bring about complete failure with the hard disk drive because of the high temperatures generated.
