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.

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.
