Resources and Documents
Lawyers, forensics investigators, and corporate IT staff who want to view and image USB mass storage devices, such as thumb drives, rely upon the CRU® WiebeTech® USB WriteBlocker™ to protect data.
The compact, highly portable USB WriteBlocker connects to USB storage devices and protects their contents during an investigation. To use, simply connect the WriteBlocker to the suspect device.
The USB WriteBlocker is compatible with USB 2.0 thumb drives and other USB mass storage class devices. It will also work with some USB 3.0 devices at USB 2.0 speed.
The USB WriteBlocker operates from bus power so you don't need to carry around a heavy power adapter. Bus power is generally sufficient for use with USB thumb drives or self-powered drive enclosures. An optional bus power boosting cable is available for use with bus-powered pocket drives that need extra power.
Use the included Forensic Software Utility to display information about connected devices and enable you to save the information in common text formats. You can download the utility from the "Resources and Documents" tab on this webpage.
