CRU USB 3.1 WriteBlocker

Designed for digital forensics investigators, legal teams, and corporate IT staff, the CRU® WiebeTech® USB 3.1 WriteBlocker delivers uncompromising data integrity during drive viewing, examination, and imaging. This hardware-based solution sits between the host computer and the USB storage device, enforcing true read-only access to the target drive so no writes can occur—whether from the operating system, software, or user actions. Lightweight, portable, and simple to deploy, it accelerates evidence collection and imaging workflows without sacrificing admissibility or chain-of-custody standards. Built by CRU WiebeTech, a trusted name in forensic hardware, the USB 3.1 WriteBlocker is purpose-built for field investigations, court-ready documentation, and incident response across diverse environments. Its USB 3.1 performance ensures fast read access to large drives while maintaining a guaranteed, hardware-enforced barrier against any unintended writes. The result is a reliable, repeatable, and legally defensible method to acquire exact copies of evidence for analysis, documentation, and disclosure.

  • Hardware-based write blocking for absolute data protection — A dedicated, non-volatile mechanism guarantees that the connected source drive cannot be written to, regardless of host software or operating system behavior. This is essential for preserving the original evidence and maintaining a defensible chain of custody during imaging and analysis.
  • USB 3.1 connectivity with fast, safe imaging — Engineered for USB 3.1 Gen 1 (5 Gbps) support, it delivers high-speed read performance essential for efficient imaging while upholding strict write-blocking. This combination shortens acquisition times without compromising data integrity or evidentiary standards.
  • Portable, field-ready design — The handheld, compact form factor fits easily into backpacks, kit bags, or evidence cabinets. Its bus-powered operation eliminates the need for an external power supply, enabling on-site imaging during investigations, legal reviews, and incident response exercises.
  • Cross-platform compatibility and workflow flexibility — Designed to work with Windows, macOS, and Linux hosts, it integrates seamlessly with standard forensic imaging tools and workflows. Whether you're producing court-ready images or performing rapid triage in the field, this write blocker keeps your process consistent and compliant.
  • Clear indicators and robust construction — Intuitive LEDs provide real-time status on the device’s operational mode, so you can verify at a glance that the drive is blocked. The unit’s rugged build supports repeated use in demanding environments, from labs to field locations.

Technical Details of CRU USB 3.1 WriteBlocker

  • Hardware write blocker — Hardware-enforced write-blocking ensures no writes reach the target USB storage device, independent of host software or drivers.

  • Power — Bus-powered via USB connection; no external power adapter required, enabling easy transport and on-site operation.
  • Drive compatibility — Supports standard USB mass storage devices used in forensic imaging workflows and investigations; optimized for common file systems encountered in evidence preservation.
  • Operating system compatibility — Designed to function with Windows, macOS, and Linux hosts without requiring specialized drivers; imaging software on the host can operate normally.
  • Indicators — Built-in LEDs provide immediate visual confirmation of the write-blocking state and device health during use.
  • Form factor and durability — Compact, rugged, and portable design suitable for fieldwork and transport between locations.

How to install CRU USB 3.1 WriteBlocker

  • Connect the CRU USB 3.1 WriteBlocker to a host computer using a USB port. Ensure the host recognizes the device and powers up normally.
  • Attach the target USB drive you plan to image to the WriteBlocker’s downstream port, following the labeling on the device to identify the correct connection point.
  • Power on or wake the host system and observe the status indicators to confirm that the drive is in a blocked/read-only state before proceeding with any imaging.
  • Launch your preferred forensic imaging or analysis software on the host. Configure the software to read from the target drive via the WriteBlocker, exactly as you would for any standard imaging workflow.
  • Begin the acquisition, ensuring your write-blocking workflow remains intact throughout the process. Validate the resulting image integrity with your standard verification methods (e.g., hash checks) as part of your routine.

Frequently asked questions

  • What is a USB 3.1 WriteBlocker? A hardware device that sits between a computer and a USB storage device to prevent any write operations, preserving the original data during imaging and analysis.
  • Why should I use a hardware write blocker? Hardware write-blocking provides tamper-evident data protection by preventing software or OS-level writes, ensuring the admissibility of evidence and accuracy of copies in forensic and legal workflows.
  • Is the WriteBlocker compatible with Windows, macOS, and Linux? Yes. It is designed to work with multiple host operating systems without requiring special drivers, enabling consistent usage across different environments.
  • Does it require external power? No. It is bus-powered through the USB connection, making it ideal for field work and locations without ready access to power sources.
  • Will it interfere with imaging speed? The device is optimized for fast read operations while maintaining strict write-blocking. Imaging times may vary with drive size and media performance, but data integrity is preserved.
  • Can I use this with all USB drives? It supports typical USB mass storage devices used in forensic work. Some unusual drives or adapters may require testing to confirm compatibility.
  • Is software configuration required? No drivers are required for operation. You can use standard forensic imaging tools with the WriteBlocker as part of your normal workflow.
