After frequent writing and deleting on hard disk, the related parts of a file (cluster) are often widely scattered, which leads to considerable delays. The program completely rearranges the structure so that all clusters of a file are directly adjacent to each other. Further functions: rescue or regenerate deleted files, restructuring of directory entries, FAT analysis, occupy defective sectors, show folder structure, change names (disk/folder) and others. ORDNE HDB supports the drivers AHDI, CHDH, ICD, Eickmann-HDplus and Vortex.
