UltraBlock FireWire - Bridge Only

SKU: W2805

The UltraBlock Firewire Bridge has gone end-of-life and is not available for purchase. 

This product has been replaced by a Firewire adapter (A1530 or A1645) for use with UltraBlock PCIe and Tableau PCIe products.

UltraBlock Firewire - The First Portable Firewire Hardware Write Blocker
The UltraBlock Firewire Forensic FireWire Bridge is the Forensic Industry’s first portable FireWire write-blocker. The UltraBlock Firewire features FireWire 800/400 and USB host connections, an integrated LCD, and six LEDs for visual status. Intelligent and efficient to use, this write-blocker deserves a place in your forensic toolkit.

The UltraBlock Firewire solves the growing challenge of imaging FireWire hard drives and Apple Macintosh® computer systems in a forensically sound manner. Built with similar operational features as our popular UltraBlock USB bridge, the UltraBlock Firewire enables reliable and efficient data acquisition in both field and lab environments.

PC Interface
FireWire 800/400, USB (1.x/2.0)
Device Interface
FireWire 800/400
Operational Mode
Write Block only


  1. UltraBlock Firewire performance is heavily dependent on block size and works best when used with an imaging application which can be configured for 128 kByte blocks.
  2. The UltraBlock Power Supply may only be used to power one UltraBlock and one Hard Drive. Do not attempt to use a single external power supply to power more than one UltraBlock and Hard Drive.
  3. Additional FireWire-A (400), FireWire-B (800), and USB Cables are available from Digital Intelligence.

Acquire Data from Firewire Storage and Apple Macintosh Computers
Imaging FireWire storage devices, including Apple Macintosh® computers, has always presented a special challenge to forensic examiners. The UltraBlock Firewire supports full multi-LUN (Logical Unit Number) write-blocked acquisitions of FireWire storage devices (including Macintosh computers booted in target disk mode). The UltraBlock Firewire identifies multiple LUNs present and prompts the user to select the appropriate LUN for imaging. The ability to image without the need to remove hard drives means you will work faster, more effectively, and with less risk of damage to evidence.

Integrated LCD Operational Display
The UltraBlock Firewire LCD functions as the information center for storage device and write-blocker information. Using the two convenient operator buttons, the user progresses through a variety of menu displays to view vital information. The monochrome LCD features 2 rows of 16 characters that are used to display status information, detailed technical information obtained from the attached FireWire device, as well as key information about the UltraBlock Firewire bridge itself.
