Tableau FAQ

Q. Whom do I contact for support of my Tableau device(s)?
A. Contact either the Authorized Guidance Software Reseller that you purchased your device from or Guidance Software Support at tableausupport@guid.com or +1 (626) 463-7977, ext. 0.

Q. Do Tableau products use any open source software?
A. Certain Tableau software applications use libraries which are licensed according to industry-standard license agreement such as the LGPL (Lesser GNU Public License). Copies of these standard license agreements may be found below: 

LGPL v2.1

The installer for certain Tableau software applications may install one or more copies of software covered under the terms of the LPGL.

LGPL v2.1 - Nokia Qt Exceptions

Certain Tableau software applications make use of the Qt software library. Nokia appends a short addendum to its version of LPGL v2.1 to cover Qt-specific expections to the terms of the standard LGPL v2.1.

Open Source Licenses for Tableau Forensic Imager [TD3]

The software distributed with the Tableau Forensic Imager contains numerous open source components.

Q. What is the difference in formats E01 and EX01?
A.

EX01 files are used in judicial environments to preserve and present digital evidence. The EX01 file is an exact copy of the contents extracted from a subject device's disk and can be mounted and read by EnCase Forensic or another program that supports the EX01 format.

The EX01 format replaced the .E01 format with the release of EnCase 7. The new format provides advanced security features such as AES256 encryption with keypairs or passwords, LZ compression, and the option for MD5 or SHA-1 hashing.

Q. What wiping standards does the Tableau TX1 support?
A. Single pass or multi-pass on hard drives. If you have an SSD that supports the secure erase ATA command, then we will give that to you as an option. 

Q. With the Tableau TX1, can we remove source and designation of first job if completed while second job is in progress?
A. We have designed the TX1 so you should be able to hot-swap source and destination as long as you do not have an operation running on it, except for PCIe. When using PCIe you need to remove or connect the adapter/cable/device when the TX1 is powered off. 

Q. On encryption for the Tableau TX1 – Is there intelligence built in to determine if the source disk is encrypted? It would be useful to have such a feature.
A. We love to get these types of requests so that we can add features like this to our road map. This is something we are currently looking into.

Q. Is there a plan to support SMB2 instead of CIFS with the Tableau TX1?
A. Yes. We plan to support SMB2.1 and SMB3 in our upcoming TX1 firmware update planned for some time in December 2017.

Q. How does the Tableau TX1 handle different types of full disk encryption?
A. We do support our own version of open source whole disk encryption on the TX1, the same we use on the TD2u, which is an open source implementation of VeraCrypt.  This allows a user to encrypt and decrypt password-based whole disk encryption using the TX1. If you are asking how we handle other types of whole-disk encryption, as in if we encounter a source drive with encryption on it, then at this time the TX1 does not detect different types of whole-disk encryption. 

Q. Is total speed and imaging time effected when the Tableau TX1 images two source drives at a time rather than one?
A. No. It does not affect the total speed or imaging time. You will see little to no degradation in performance with the TX1 when simultaneously imaging.  

Q. What performance will I get with the Tableau TX1 when imaging two SATA sources to two SATA destinations and how long will it take to image?
A. During our performance testing for the TX1, when simultaneously imaging two 128 GB SATA SSD to two 256 GB SATA SSD, we recorded speeds of about 490 MB/sec each job. The TX1 completed both jobs in approximately 9 minutes.

Q. Can I simultaneously copy content from one external hard drive to two other hard drives via USB 3.0 on the Tableau TX1?
A. Yes. There are some conveniently available USB 3.0 and USB 3.1 hubs you can purchase and use to connect more than one USB drive to the source or destination side. Simply connect that to either the source or destination USB 3.0 port on the TX1. When you setup your job, you then just select the one source and each destination, choose either clone or image and then you are ready to start your operation.

Q. Do you have any stats on the throughput of the Tableau TX1 based on performance and data imaging sizes?
A. Yes. Please reference the OnDemand webinar “Three Ways to Increase Your Case Productivity with the Tableau TX1 Forensic Imager” within the Resources section of our website for this information. 

Q. With the Tableau TD2u Forensic Duplicator, the biggest problems we have are the cable clips breaking which runs the risk of the cables detaching from the machine. Have there been upgrades made to this component on the Tableau TX1 cables?
A.

We did receive some reports of issues with the clips that you pinch for the connector of the SATA/SAS cable (TC4-8-R2) that came with the Tableau TD2u. We did recently improve that cable by having our manufacturer make the connector more robust, and this cable is now shipping with all new products that use it, including the TD2u.  The new version of this cable has a white dot on the side of the connector as a reference.  If you have cables with broken clips, then please contact Tableau Support or your Authorized Reseller and we would be happy to get some new cables to you.

With TX1, we use a new SATA/SAS cable (TC4-8-R3), which has a SATA/SAS connector that is rotated 180 degrees compared to the previous one (TC4-8-R2), so that it can be inserted directly into the TX1  without twisting cable, and it has the same more-robust connector clips.

Q. Does the Tableau TX1 Forensic Imager also work as a write blocker?
A. Yes. Always, and in all modes, the source media (connected to the left side) are write-blocked. 

Q. How does the Tableau TX1 Forensic Imager Compare to the Logicube Forensic Falcon?
A. When it comes to individual operations, the Tableau TX1 is certainly faster than the Falcon, except for cases where the source media or destination media are going to be the speed limiters. However, when we start talking about network operations, it is impossible for a 1 GbE device to compare to a 10 GbE device such as the TX1. Also, when we start doing simultaneous operations, the performance degradation for the TX1 is none or very little, which is much less than any other product, such as the Falcon. The TX1 is a powerful device and it multi-tasks very well. TX1 also costs much less, weighs less, comes with a better factory warranty, is easier to use, and has easier to update firmware.
