Meet Guardonix

USB3.0 Writeblocker and Stabilizer

A better writeblocker which will not allow your data acquisition process to be interrupted due to intermittent read instabilities.



Enables forensic acquisition of USB storage devices by blocking all write commands to preserve data integrity.

Prevents Windows from freezing, crashing, and/or dropping USB storage devices due to bad sectors or other read instability issues.

Professional Edition

Speeds up bad sector processing by 5-25+ times, allowing Windows-based tools to work with highly unstable drives.

Extended configuration options and status information which shows how well data acquisition is proceeding in real-time.

USB protocol requires the PC and storage device to be in constant synchronization with one another. If the storage device fails to respond quickly enough, or responds irregularly due to bad sectors or other read instability issues then it may lose its current state and become desynchronized with the PC. The only option for Windows to regain access to the device is to reinitialize the whole connection, which means re-mounting the USB device in the system, thereby interrupting any data acquisition procedures which are currently in progress.

Guardonix hardware stands between the PC and the storage device, making sure that the connection to the PC is always well-maintained, regardless of what’s happening with the storage device. This way even if the storage device becomes desynchronized, only it’s connection to Guardonix hardware will be reinitialized, which will not have any impact on the PC, allowing data acquisition to proceed without interruption. Guardonix hardware even allows for the storage device to be entirely disconnected, during which time the PC will simply wait until it’s reconnected before seamlessly continuing with data acquisition.
