5.6 Safe Disposal of Data & Computer Equipment
Legislation
Waste Electrical and Electronic Equipment Recycling (WEEE)
It is regulated to reduce the amount of waste electrical and electronic equipment ( WEEE ) incinerated or sent to landfill sites. This legislation sets out how organisations should dispose of computer equipment safely.
WEEE aims to reduce the amount of waste electrical and electronic equipment ending up in landfills and requires the collection, treatment, recycling and environmentally sound disposal of equipment.

Overwriting Data
It is the process of replacing old information with new information.
This is simply deleting data and adding new data to the storage device.
It only works when the storage media is undamaged and therefore still writable. If the media degrades over time, then the method won't be of any use, meaning that the drive will need to be physically destroyed. While it is cost effective compared to other methods, it's not free.
Electromagnetic Wipe
This is a device which will use magnetic irradiation to wipe data off a storage device.
It completely gets rid of the data.
Completely been rid of the data. Overwritten data could be overwritten from the start again.
Physical Destruction
This is simply destroying the device physically so it is unusable and data cannot be retrieved from it.
Many organisations first electromagnetically wipe the device and then physically destroy it to be 100% sure no data will ever fall into the wrong hands.
Companies use this measure to ensure data cannot be retrieved as they have made sure when physically destructing the data, the data cannot be opened, checked or retrieved again. They do this by shredding the data, or by making sure the data has been deleted off the software/network.
