5. Remove the drive from the drive bay with care. Follow the safety notes: 41<br />

<br />

<br />

Handle the SSD with care, keep it in the protective anti-static sleeve<br />

Do not touch connectors on the SSD drive<br />

To minimise static electricity, touch the desktop case before handling the SSD.<br />

8.5 Equipment and Tools Required<br />

The following equipment and tools are needed:<br />

<br />

<br />

<br />

Portable battery chargers<br />

Antistatic bags, antistatic bubble wrap, Faraday bags/boxes, cable ties, evidence bags, evidence tape,<br />

packing materials (avoid materials that can produce static electricity), markers<br />

Pliers, electric screwdrivers with various heads.<br />

8.6 Document Phase<br />

8.6.1 Photographing/Recording the Scene<br />

Photographing or video recording 42 is the crucial part of the document phase. It should be the first step taken<br />

by the SOF operator on arrival (together with the scan phase). This will also accurately depict the condition of<br />

the scene prior to any evidence collection or disruption that will probably happen during processing [28].<br />

Ideally, video recording goes from the overall scene down to the smallest pieces of the evidence. As mentioned<br />

before in this chapter, do not forget to record the status of the monitor screen. 43 Photographs or video should<br />

also be taken of the rear of information processing equipment, to accurately display how the cables are<br />

connected. It is helpful even if the equipment is not to be seized: as it is present, it should be recorded.<br />

As described in paragraph 10.3 – ‘Documentation of Evidence’, photographing and recording the scene are<br />

important. Cameras providing a 360° picture could be helpful, not only for documenting the scene, but also for<br />

scanning and identifying devices. If a convenient video streaming can be originated 44 from the tactical site<br />

towards the tactical operations centre (TOC), forensics experts can remotely advice SOF operators. The video<br />

streaming should also prevent any form of operators’ identification by using blurring techniques, as explained<br />

in Chapter 10 – ‘Chain of Custody.<br />

8.6.2 Packaging and Labelling<br />

All evidence collected should be marked as exhibits so that they can be easily identified at a later date [39]. All<br />

exhibits must be properly seized, labelled, transported, and handled for evidence recovery purposes. The<br />

labelling or marking of the evidence begins the chain of custody of the items of evidence (see Chapter 10 –<br />

‘Chain of Custody‘). The label should contain at least the following information [38]: description of the item,<br />

date, location of collection, operator name or identifier, and brand name. The labels must be affixed to all<br />

41 SanDisk [40] provides an installation guide with safety notes for handling SSD drives.<br />

42 It should be completed prior to any evidence seizure but within the short timeframe of the SOF strike it can be done parallel [28].<br />

44 Chapter 9 – ‘Sustaining the Data‘ covers techniques to create communication channels; yet convenient bandwidth for high quality video<br />

streaming is a challenging requirement, so most likely only 360° images can be provided.<br />
