In order to solve data recovery problems in computer forensics
this paper proposes a new algorithm based on NTFS.By analyzing the structure of NFTS
this algorithm classifies data into three varieties and handles them differently.Organized-impossible data is recovered and taken forensics by the distributing of the words.Organized-possible data is recovered and taken forensics by the references records of NTFS.Result shows that this algorithm could rebuild deleted data and make foundation for forensics.
