DTI DATA NZ's computer forensic hardware allows evidentially sound copies to be made of all areas of a computer’s hard drive. This is the method accepted for the production of computer based evidence by the major law enforcement agencies in the UK and around the world. The image secured is as close a representation of the original hard disk as possible. Indeed, it is argued by many that it is better than the original. The image allows you to access data of which the original user was unaware or thought deleted.

DTI DATA NZ provides two ranges of imaging hardware for computer investigation professionals:
Windows based high performance Imaging Systems based on a high performance mobile or laboratory workstation PC. The image may be recorded DAT, LTO media or disk file. Two images may be recorded simultaneously. A special feature of these systems is the automatic write-protection of the target or suspect hard drive. Images created may then be uploaded to a workstation PC for processing using the unique Processing and Investigation Software.

Legacy DOS based Imagers, based upon the clean boot method of operation. The image is recorded directly to DDS DAT (digital data storage – digital audio tape). Two images may be recorded simultaneously. Images created may then be uploaded to a workstation PC for processing using the unique Processing and Investigation Software.
