Your investment in WiebeTech products is backed up by our free technical support for the lifetime of the product. WiebeTech provides a 3-year limited warranty for this product. USB drives via USB cable (if the device class is USB Mass Storage Device and it does not use proprietary firmware).USB Thumb Drives USB 3.1/3.0/2.0 thumb drives with either a Type-A or Type-C connector. ![]() To see more information about these products, you can start by choosing a product from the entire WiebeTech product line. The Ditto Forensic FieldStation is ideal for remote data analysis and capture and it replaces the need for a laptop or other host machine during data acquisition.The LCD and menu system make it convenient to view drive information, error/warning messages, or remove HPA/DCOs. The DriveDock family of products provides fast write-blocked access to suspect drives.It provides easy, write-blocked access to a variety of flash media, including SD and CF cards. The Media WriteBlocker is highly portable, with compact lightweight design.Through its WiebeTech line of digital investigation products, CRU offers a wide variety of hardware write-blocking solutions. This makes them easy to use and makes functionality clear to users. Hardware devices that write block also provide visual indication of function through LEDs and switches. Hardware write blockers provide built in interfaces to a number of storage devices, and can connect to other types of storage with adapters. Some of its functions include monitoring and filtering any activity that is transmitted or received between its interface connections to the computer and the storage device. The primary purpose of a hardware write blocker is to intercept and prevent (or ‘block’) any modifying command operation from ever reaching the storage device. Programs running in the DOS environment can, in addition to direct access via the drive controller, use two other interfaces: DOS service interface (interrupt 0x21) or BIOS service interface (interrupt 0x13). The main difference between the two types is that software write blockers are installed on a forensic computer workstation, whereas hardware write blockers have write blocking software installed on a controller chip inside a portable physical device.Īs determined by NIST’s Software Write Block specifications, a software write block tool operates by monitoring and filtering drive I/O commands sent from an application or OS through a given access interface. Software and hardware write blockers do the same job. The tool shall not prevent any operations to a drive that is not protected.The tool shall not prevent obtaining any information from or about any drive.The tool shall not allow a protected drive to be changed.NIST‘s general write blocking requirements hold that: A write blocker, when used properly, can guarantee the protection of the data chain of custody. What are write blockers?Ī write blocker is any tool that permits read-only access to data storage devices without compromising the integrity of the data. The second two bullet points refer to software and hardware write blockers. Further, not all drives have the ability to use jumpers. The first bullet point speaks of jumpers, but there may be times when the suspect drive’s jumper settings are not easily accessible. Use a hard disk write block tool to intercept any inadvertent disk writes. ![]()
