2 Quick Start Guide

2.1 Turning On

1. Connect the supplied 12V 5A power supply (PSU) lead.

2. Remo e any flash card and switch on (rear panel switch up).

3. A line of dots will appear on the display and PUMA will start in about 25 seconds.

2.2 Making Master and Working Copies of a Flash Card

1. Check that the displayed time and date are correct.

2. Insert the flash card into the appropriate front panel slot. The display will show the

card’s size and number of files. A USB stick may be plugged into one of the USB

sockets on the rear panel or front panel.

3. Press the eject button on the DVD/Blu-ray dri e to eject the disk tray. Place a BD(1),

DVD or CD in the tray. For the Dual Dri e ersion, press the eject button on the

external dri e and place a blank disk of the same size on the tray and close the

drawer.

4. Press the TRANSFER button to start the transfer.

a) A Master copy is produced first. This consists of the transfer of the data from the

card to the disk and a erification read pass. On successful completion the

Master disk will be ejected and the checksum of the flash card and disk will be

shown. This can be noted down for future reference. Where multiple disks are

needed, follow the on-screen instructions and note down the separate disk

checksums as well as the final checksum for the card and whole backup.

Single Dri e:

b) Remo e the Master Copy disk and place a new disk on the tray. Press the lower

soft key marked “Continue” to proceed. The Working copy is now produced. On

successful completion the disk(s) will be automatically ejected.

Dual Dri e:

b) The Working copy will be ejected at the same time as the Master. Remo e the

Master and Working Copy disks.

c) The flash card may now be wiped and re-formatted. Press “N” when prompted if

this is NOT required.

The Transfer is now complete.

Note: If further copies are required, do not wipe the card and use the appropriate

functions a ailable in the “Menu”. Press “Menu” soft key and the Up/Down cursor keys.

2.3 Turning Off

Press the I/O button below the green LED to shutdown. When “Switch Off” is displayed,

turn off the rear panel Power Switch.

3 Detailed Operation

3.1 Setting up and Powering PUMA

Using in a vehicle. PUMA requires a regulated 12V power supply. If PUMA is to be

used in a vehicle please use the 12V stabiliser available from your supplier or

Cypher Technology Ltd NOT the vehicle power direct.

1. Remove any flash card.

2. Switch on the Power Switch on the rear panel (switch up).

3. After about 25 seconds the PUMA program will start and the system is ready for use.

4. PUMA has various settings that control the format of the Master and working disks.

These are saved after any changes are made and will normally not require and

further attention. Normally a “Compact Master” is used and a “File Copy” working

disks. These settings can be inspected and changed in the Settings sub-menu.

5. Check that the displayed time and date are correct. If not use the “Adjust Time”

menu function to adjust the time and date (Section 3.8.5).

3.2 Making Evidential backup of Flash ard or USB stick

PUMA has an automated process for making an evidential archive of a flash storage

device. This process is initiated by pressing the [Transfer] key. The Transfer consists of

the sequence: Make Master Verify Master Make Working Copy and then Wipe and

format the flash card.

1. Place the flash card in the appropriate slot. If a USB drive is to be archived plug this

into either of the USB slots in the rear panel or the slot in the front panel (M1.3 only).

An extension lead may be required for bulky USB flash drives

2. Place a blank CD-R or DVD +/- R or BD-R(1) in the drive. The Master is generated

first. The size of the flash card is shown on the display when it is inserted. A CD will

hold 730MB a standard DVD 4 700 MB and a Blu-ray 25GB - 100GB. Where the

data size is larger than the disk size multiple disks will be produced. These disks will

be automatically numbered as Master Disk #1 Master Disk #2 etc. The Master Copy

has a log file which contains the time and date stamp of the backup as shown on the

display on the front of the machine as well as other meta data. For a Dual Drive

PUMA place a blank disk of the same size as the Master in the external writer and

close the tray.

3. Press the Transfer button. The automated transfer and verify process begins.

During the transfer the whole of the card is scanned not just the file data. The

display shows the % done and an estimate of time to go. (The “Cancel” soft key

allows the transfer to be aborted)

4. When complete PUMA ejects the verified Master Disk and displays the 8 digit

Checksum. This Checksum should be noted down.

(Multiple disk transfer - If the data size is bigger than the disk size, further disks will be

requested. Each disk has its own checksum, which is displayed at the end of each disk

transfer. hen all the data has been transferred, no new disks will be requested. Press

Cypher Technology Ltd V2.8(14) March 2020 7

{Continue} and the checksum of the whole Master Image will be shown. This should also

be noted down. This final checksum is the same as the checksum produced for the card.)

If the process was not successful, the disk(s) will not be ejected and an error

message will be displayed and the user will be prompted to re-burn that disk.

5. P MA then prompts for another blank disk to be inserted for the Working Copy. If

the size of the files on the flash card is bigger than the disk size, further disks will be

requested.

6. Where an external drive is connected and the Dual Drive option is enabled, the

Working copy will be made on the external writer, when a blank disk is inserted at

the same time as the blank Master disk.

7. If the whole Transfer process completed successfully the user will be prompted to

wipe the Flash card:

Press {Y} to wipe flash card or {N} to proceed without wiping card. After the card is

wiped it is automatically partitioned and re-formatted with a FAT32 file system.

The Transfer process is now complete. A new flash card may be inserted.

3.3 Turning Off

It is good practice to remove any flash cards or SB sticks from P MA before powering

down.

Press the I/O button below the green LED to shutdown. Press {Y} to confirm. When

“Switch Off” is displayed, turn off the rear panel Power Switch.

If {N} is pressed the Software Revision and Serial Number (where appropriate) will be

displayed and P MA will resume operation.

3.4 Checking for External Drive and PUMA Statu Information

Press the I/O button below the green LED to shutdown. If {N} is then pressed the

Screen will show if an external drive is connected and also then show the Software

Revision and Serial Number (where appropriate) and P MA will resume operation.

3.5 Menu Sy tem

3.6 Main Menu Items

3.6.1 ake Working Copy (make simple file copy)

This is function will create a Working Copy from the flash card or USB stick. Normally all

files are copied, including hidden and system files. ther Working Copy formats can be

selected in the Settings sub-menu.

3.6.2 ake Encrypted Copy

This is an optional feature. It is used to make an AES 256 encrypted and password

protected copy of the files on the flash card. PUMA will automatically generate a

Cypher Technology Ltd V2.8(14) March 2020 9

pseudo-random high security 14 character password. It is highly recommended that

this be used for security reasons. Alternatively a password may be entered using the

cursor keys. The [ ],[>] keys select the character position and the [up],[down] keys

select the character value. Press the {Use} softkey when the correct password is shown

AND it has been noted down.

To Decrypt Files on the Encrypted Disk

A Decrypter program is copied automatically to the encrypted disk. To access the

encrypted files, insert the disk into a Windows XP or later PC. The encrypted files can

be seen in the “Files” folder. These files can be copied in the normal way but cannot be

accessed until decrypted.

To decrypt, double click on the Decrypter icon in the top-level of the CD or DVD. Select

the file or files to be decrypted using the Decrypter browser. When the selection is

complete, click the Decrypt button. You will be prompted for the password and then to

select a destination folder into which to copy the decrypted files. If the password is

correct the files will be decrypted.

3.6.3 Make Master Copy

This function will create a Master Disk fro the flash card or USB stick. The PUMA

Master contains all the data from the flash card on a write-once optical disk.

3.6.4 Hard Disk Master

This function creates a File Master copy of a large hard disk (or flash card or USB drive)

on a second, empty hard drive.

All files are copied along with a log file that contains the MD5 hash codes of all the files

so that the transferred material can be verified for added protection. It does not scan

unused areas of the drive and therefore should normally only be used where a full bit for

bit Master is not required. The HD Master can also be used where it is impractical to

create a standard PUMA Master and where, therefore, this could be regarded as “best

practice”

First connect the empty backup drive to one of the USB ports on PUMA (in the top level

of the Menu). The display should show the size of the disk and 0 files. If it shows any

files or says “No file system” then the drive should be formatted using the Menu “Format

card” option. After the format, exit the Menu and check that the display is now showing

0 files.

Then press {Menu} and scroll down to “Make HD Master”. Connect the source evidential

drive and press and {Go}. The destination drive is automatically chosen as the empty

drive.

Several backups can be made to the same drive and the destination drive will be

automatically recognised after its first use.

3.6.5 Disk to Disk

Opens sub menu for all disk to disk copy functions (dual drive PUMAs only)

3.6.6 Wipe Flash Card

This function will perform a forensic wipe of the flash card. No data will be recoverable

from the card after this operation (see below).
