rdd – forensic copy software

rdd is a forensic copy program developed at and used by the Netherlands Forensic Institute (NFI).

Specifically, rdd is a file and device copying utility that includes features that are useful in a forensic environment. In particular, rdd can compute cryptographic hashes over the data it copies, which is an important property in a forensic operating environment. The software is also robust with respect to read errors, and can copy data across a network.

rdd can be run in local mode, in client mode, and in server mode.

Features include:

  • Checksumming (Adler32 and CRC32) – computes an MD5 or a SHA1 hash value over the input bytes and the zero bytes it substitutes for blocks it cannot read.
  • Access the device using the raw device.
  • Designed to handle unfriendly source media.
