DFERRELL  Data Rescue II worked very well in recovering data from a damaged hard drive that would not mount. Their tech support was available and very helpful when I was trying the product as a demo and continued with the same fast response when I was convinced that it would work for me and purchased the full version. Features were easy to use, recovery was nearly 100%. It took only a matter of a few hours to scan and recover my data. Prosoft gets 5 stars from me.
