The USB printer must support raw ASCII printing.
Resetting and Clearing Internally Stored
Information
Some forensic and security applications require that the user be aware of the kinds of
information that the duplicator can store. In some cases, you may want to know what, if any,
information is preserved by the unit from one acquisition to the next. Or you might be in
security-sensitive environments and need to be able to sanitize equipment before it is
removed.
The TD2u has three separate non-volatile memories.
The first non-volatile memory is a flash device which is used to store the firmware and serial
number of the TD2u. The firmware can be updated using the Tableau Firmware Update utility
(available from
www.guidancesoftware.com/tableau ). This flash device is never used to record
any user-specific or acquisition-specific information.
The second non-volatile memory is a separate flash device used to store two different types of
information: configuration settings and logs. Configuration settings include the following:
l
User/operator name (entered via Configuration Wizard or Setup Menu).
l
Startup mode of operation (entered via Configuration Wizard or Setup Menu).
l
Error handling settings (error recovery strategy and error counter limits).
l
Default directory naming conventions for disk-to-file duplication (directory name format).
l
Default file naming conventions for disk-to-file duplication (file name format).
l
Default file format conventions (segment size, etc.).
l
Last-used case ID and case notes.
l
User preferences for prompts (directory name, file name, case information).
This second flash also records up to the most recent tasks performed by the duplicator. A task
in this context is any operation which operates on a disk device, including duplication,
formatting, wiping, hashing, blank checking, and HPA/DCO operations. Logs include detailed
information about each disk device attached to the TD2u; this includes make/model, serial
number, capacity, and so on.
