  • Ideal for Computer Forensic Investigation
  • Legal Evidence Preservation
  • Prevent Data Corruption
  • Prevent Security Breaches
  • Prevent Data Loss due to Human Error
Computer Forensic investigation may be accomplished without equivocation concerning modification of the data. When Model SR14 SCSI Write Blocker is employed, data bases may be read, but, not written to. Connects to any SCSI implementation as SCSI Universal interface is employed to automatically detect SCSI LVD, HVD or SE mode
This SCSI Converter has two unique features: 1. A Universal SCSI interface that automatically detects and switches to the SE, LVD or HVD mode depending on the peripherals connected to it. 2. A feature that blocks all SCSI WRITE commands to prevent writing to peripherals

With the rigors of evidence standards in mind, hardware Write Blocking is a must. Paralan's SCSI Write Blocker allows data to be read at full speed, however, it will block any and all write commands thus preventing the possibility of writing to, or formatting the drive under examination. To prevent any system problems when write commands are ignored, a false acknowledge of writing is reported to the host computer.

Any software solution used to examine a drive under investigation has the potential (overt or accidental) to write to the drive. By using a Hardware Write Blocking interface, Computer Forensic Investigation may be accomplished without fear of compromising the data on the drive.
The SCSI interface to the drive may be LVD, HVD, or SE because the SR14 and SR15 are equipped with a Paralan Universal SCSI interface, just connect cables and turn it on.
