Imaging Settings Menu, page 1
Checksum: Select MD5, SHA1, SHA224, SHA256, SHA384, SHA512 or skip checksum
calculation (“Do not calculate”). This feature is provided for forensic computer
investigation and similar applications in order to meet procedural standards.
Checksum calculation will reduce imaging speed and disable certain data recovery
features (such as multi-pass imaging).
Imaging Mode: Image all sectors or only sectors that contain data (partition tables,
user files, file system structures, etc).
Imaging occupied sectors will significantly reduce imaging time; however, this mode
is only reliable when the file system on the Source hard drive is perfectly healthy.
When imaging a hard drive with critical data, or when the hard drive is damaged, we
strongly advise using the All Sectors option.
Reverse: Image sectors in reverse order. Last sectors of the hard drive will be
imaged first, and sectors at the beginning of the surface will be imaged last. This
mode sometimes improves success rates when imaging unstable hard drives.
Pass settings: The Bandura is capable of applying 1 to 5 imaging passes to
maximize data extraction. Each pass applies different values for the below settings in
order to suit different data recovery scenarios. Typically, multi-pass imaging options
are designed to apply a quick first-pass to pull data while minimize strain to the hard
5
drive, and later imaging passes apply slower, more precise settings in order to make
sure every possible bit of data is being extracted.
Timeout: length of pause after error encountered
Sector Skip: length of forward jump after read error or timeout encountered
2 pass (few or no defects): Works best for hard drives that do not have many
uncorrectable (bad) sectors.
Pass #1

More features are accessible on the second settings screen:
Imaging Settings Menu, page 2
Max number of power cycles: This setting limits the number of power cycles that
can be applied during imaging before the function is terminated. Power cycles are
applied when the Bandura fails to reset a frozen hard drive during imaging (Bandura
cuts power to the hard drive and restarts it). Setting options: 2, 5, 10, 100.
Pattern for unreadable sectors: When imaging, the Bandura copies every sector on
the source hard drive to the corresponding sector on the Target drive (sector with
same LBA). If there is an unreadable sector (bad sector) on the source drive, the
Bandura will write a HEX pattern to the corresponding sector on the Target drive.
This setting allows the user to specify the HEX pattern being written to the Target
drive. Custom patterns of any length up to 512 bytes can be set.
To specify a custom pattern:
1. Create a text file “Patterns.txt” using a PC
2. In the file, write one pattern per line HEX codes (no spaces)
3. Upload the file onto a USB flash device
4. Plug the USB flash device into Bandura’s rear USB port
5. Select the desired pattern in the menu.
8
Fill unreadable sectors: Whether to fill unreadable sectors with the specified
pattern. When disabled, Bandura will not write anything onto target media on source
read error. This feature was added in the firmware version 1.0.4.
Diagnose before imaging: Run a diagnostic sequence on the Source drive before
imaging is started. This feature is meant to inform the user about the state of the
hard drive in order to determine the best imaging approach.
After imaging begins, the following screen is displayed:
Imaging in progress
This screen displays real-time status.
• Tap Show Log button to browse current log entries (will not stop imaging
process).
9
• Tap Pause button to temporarily stop the function. Imaging menu will then
appear with Resume Imaging and Delete Session options:
Imaging menu
Tapping Delete Session will result in a complete termination of the current imaging
session without the option to resume.
Storing imaging progress and log files
In order to pause imaging and then resume it at a later time, or to save log files, plug
a USB flash media device into the rear USB port of the Bandura unit. Use any USB
flash media (formatted as FAT-16 or FAT-32) with at least 1 GB of free space.
Imaging settings, progress, and log files will automatically be saved onto the flash
device.
Please note that one USB flash device can only contain one imaging session (i.e.,
imaging progress for only one hard drive).
To store log files from complete imaging sessions, simply plug a USB flash device
into the Bandura and the files will be stored automatically. Multiple log files can be
stored on a single USB flash device.
10
Diagnosing hard drives
The Bandura has a powerful and fully automated hard drive diagnosis engine. It
applies a very complex and effective chain of diagnostic measures with one simple
tap of the display screen.
To launch Diagnostics, simply tap Diagnose in the Main menu. The Bandura will
automatically diagnose the HDD circuit board, headstack, media surface, firmware,
and partitions/file systems:
Diagnosis in Progress
To view log files for the function in progress, tap the Show log button (see above
screenshot). A streaming, real-time log of all actions being taken and diagnostic
results will be displayed (see below screenshot):
11
Real-time log
A results screen will appear after the circuit board, headstack, media surface,
firmware, and partitions/file systems have been diagnosed:
Results Screen
12
The user then has the option of continuing on to a full media scan by tapping
Continue:
Media Scan
The media scan verifies every sector on the HDD surface area in order to identify
possible errors (bad sectors).
13
Erasing hard drives
The Bandura securely wipes/erases data from hard drives. After wiping, it verifies
that the data has been properly erased by scanning selected sectors (spot-checking).
To start erasing, plug the hard drive into the Target HDD channel. Disks can only be
erased when plugged in to the Target channel because the Source channel is writeprotected to ensure data security.
Access the Erase Menu by tapping the Erase button on the Main Menu:
Erase Menu
To start erasing immediately, tap Start Erasing target disk. Settings from the
previous erasing session will be used.
To adjust settings, tap Settings.
14
Erase Settings Menu
In the Erase Settings Menu, tap either of the options to change the setting. After
parameters are set, tap Back to Erase to go back to the Erase Menu.
There are several wipe methods available in Bandura:
Fill with pattern: Specify custom patterns of any length up to 512 bytes. The
specified pattern will be written repetitively to the Target hard drive. If no pattern is
specified, the Bandura will write zero pattern (0000) to all sectors of the Target hard
drive.
To specify a custom pattern:
1. Create a text file “Patterns.txt” using a PC
2. In the file, write one pattern per line HEX codes (no spaces)
3. Upload the file onto a USB flash device
4. Plug the USB flash device into Bandura’s rear USB port
5. Select the desired pattern in the menu.
This is the quickest wiping method.
Fill with LBA: Fill each sector with the characters that represent its LBA (Logical
Block Address). This option is usually used for research purposes.
15
Security Erase: Executes the hard drive’s Security Erase function (manufacturer
specific).
Notes:
1. Once this function is started, it cannot be stopped until the erase sequence is
complete. If the hard drive is shut down before the sequence is complete, the
hard drive might be locked with an empty password.
2. This method is not always reliable.
NIST 800-88: This option will wipe the hard drive according to the NIST 800-88
standard.
DoD 5220.22-M: This option will wipe the hard drive according to the DoD 5220.22M standard.
16
After the function is started, the Erasing in progress, display will appear:
Erasing in Progress
• To terminate the function, tap Stop
•
To view real-time log files of the process, tap Show log
17
Comparing hard drives
The Bandura’s disk comparison feature compares each sector of the Source disk to
the corresponding sector of the Target disk and identifies any sectors that have
differences (non-matching bits).
To start the function, tap Compare on the Main Menu (function will start
immediately):
Comparison in Progress
• To terminate the function, tap Stop
• To view a real-time log of the functions in progress, tap Show Log
