There are three ways of destroying data on a hard disk drive we offer two.

Physical Destruction

Overwriting

All data destruction carried out by TSI is certified and fully traceable using the manufacturer's serial numbers. We can return the destroyed drive to the customer or we can arrange to have the drive recycled. We can also complete the destruction on site in some cases.

Physical Destruction

This method is the preferable method for destroying data. We can offer two methods of physical destruction of your data.

Abrasive disk destruction
This method offers ultimate piece of mind. This method involves disassembling the disk drive to remove the magnetic layers from the disk substrates using abrasives.
Confidence level: Very high

Motor and disk stack crushing
This method involves using a specialist piece of equipment to damage the drives motor housing and bend the disks inside the drive. This method of destruction can be carried out onsite and we also hire this equipment to customers who wish to carry out their own data destruction.
Confidence level: High

With both of these methods we destroy key components on the drives logic card. Examples of key components would be HDCs, Microcontrollers and Memory modules.

Overwriting

We offer two methods of overwriting.

The first is US DOD 5220.22-M (8-306./E,C and E) [7 pass] and the second is the 35 pass algorithm developed by New Zealand cryptographer Peter Gutmann. Both of these ensure the drive is reusable.

US DOD 5220.22-M (8-306./E,C and E)
This method involves writing all sectors on the drive seven times using randomised data patterns and set characters and their complement. This method is suitable for home users.
Confidence level: Medium

35 Pass algorithm
This method writes all sectors on the drive 35 times using set and randomised data patterns in a precise order. This method was developed by world renowned cryptographer Peter Gutmann. This method is the most secure of all the overwriting algorithms.
Confidence level: High

Degaussing

We do not offer degaussing as a method of data destruction because the maximum coercive field of 5000 Oersteds available on commercial degauss magnets potentially is not intensive enough to penetrate the hard drive casing and destroy the data residing on the hard drives disks.
Confidence level: Low
