4.16 How is the Master Copy used?

4.16.1 Master Copy – The ultimate evidential exhibit

The Master Copy contains a single file called “flash.img” which is a bit for bit copy of the

whole of the Flash card. This includes the files, deleted files, the file system, partition

information and all historical file data. As such it provides the most secure, evidential

backup and allows the most complete evidential audit trail. It contains everything that

was on the Flash card and is the same size (in Kbytes) as the Flash card. The flash.img

file has its time created, modified and accessed values set to the time of the start of the

transfer. This time is taken from the system time as displayed on the front panel of the

machine at start-up.

When the flash card is bigger than the disk size, multiple disks are needed and each

disk will contain part of the image. The first disk will contain a file called flash1.img , the

second disk, flash2.img etc. These part images may be combined to form a single,

complete image file (see Section 4.18 ).

The Master Copy can be used in two ways. On a PC with an Image Viewer program or

by restoring the image back to a Flash card or USB disk.

4.17 Accessing the Master Copy with WinImage

Firstly, the flash.img file on the Master Copy disk can be opened with a disk image

viewer program. Such a program is WinImage, a trial version of which may be

downloaded from: http://www.winimage.com/download.htm
