Digital Forensic Tool- Write-Blocker

Write-Blocker
   
         A write-blocker is a security tool that prevents unnecessary or malicious data from getting into the digital records that are being saved in the collection's computer. Specifically, a write-blocker allows for the computer to pull data from the connected media without the computer sending any information to the connected media, which stops any unwanted data transferring. There are different types of hardware write-blockers, the most common being a write-blocker that connects using a USB port. A specific brand of write-blocker is the T8-R2 Forensic USB Bridge which uses the Tableau IMager (TIM) and has transfer speeds up to ninety percent. The T8-R2 is compatible with USB thumb drives, external USB disk drives, Apple iPod's and USB based cameras with card reader capability. The T8-R2 works with USB 2.0 and FireWire400 to connect to computers which enhances usability with forensic hosts and software tools. Specific operating systems that the T8-R2 works with are Windows, Macintosh OS X, and most Linux distributions. The T8-R2 has a one year warranty for parts and workmanship from the date of purchase.
