mftrebuilder

A simple tool to retrieve damaged MFT files, based on RAW data. The corrupted files are compared with RAW unnamed data files. If the size of a corrupted MFT file is equal to an RAW file, the file is replaced.This allows corrupted files from one drive to be restored to another, after the user recovers large amounts of RAW files (eg music, photos, mp3, jpg, etc.). All files with name and date, which are corrupted, are analisados com cada arquivo RAW. Caso o tamanho e extensão dos dois arquivos sejam iguais, o arquivo danificado é substituído com o arquivo RAW correspondente.
