SeqBox - A single file container/archive that can be reconstructed even after total loss of file system structures

  •    Python

An SBX container exists both as a normal file in a mounted file system, and as a collection of recognizable blocks at a lower level.SBX blocks have a size sub-multiple/equal to that of a sector, so they can survive any level of fragmentation. Each block have a minimal header that include a unique file identifier, block sequence number, checksum, version. Additional, non critical info/metadata are contained in block 0 (like name, file size, crypto-hash, other attributes, etc.).

BlockHashLoc - Recover files using lists of blocks hashes, bypassing the File System entirely

  •    Python

The purpose of BlockHashLoc is to enable the recovery of files after total loss of File System structures, or without even knowing what FS was used in the first place.The way it can recover a given file is by keeping a (small) parallel BHL file with a list of crypto-hashes of all the blocks (of selectable size) that compose it. So it's then possible to read blocks from a disk image/volume, calculate their hashes, compare them with the saved ones and rebuild the original file.
