ANDYHIGGINS  A catastrophic backup failure deleted three years worth of photographs from my external Lacie hard-drives so I urgently went in search of data recovery software. An initial Google search brought up Data Rescue II which was further validated by my local Apple store when I asked their advice. After an online purchase I installed and followed the step-by-step guide. The scan of deleted space of a 500GB drive took about 8 hours and categorised all the file types for recovery. All seemed to be perfect until....

Adobe DNG files (industry standard RAW digital negatives) were incorrectly identified as TIFFs of only around 200KB instead of their true size of 10MB+ This was a little alarming! I raised a support ticket via Prosoft's website who responded immediately with a fix - a file module designed for these types of files. Unfortunately it was only partially successful so I contacted Technical Support for advice. They requested 10 sample .DNG files to allow them to custom build, at no cost, a file module which arrived within a few hours. This was 100% SUCCESSFUL.

I couldn't ask for better service or a better product.
