Carving tools help you recover deleted files
IT experts and investigators have many reasons for reconstructing deleted files. Whether an intruder has deleted a log to conceal an attack or a user has destroyed a digital photo collection with an accidental rm -rf, you might someday face the need to recover deleted data. In the past, recovery experts could easily retrieve a lost file because an earlier generation of filesystems simply deleted the directory entry. The meta information that described the physical location of the data on the disk was preserved, and tools like The Coroner's Toolkit (TCT [1]) and The Sleuth Kit (TSK [2]) could uncover the information necessary for restoring the file.
Today, many filesystems delete the full set of meta information, leaving the data blocks. Putting these pieces together correctly is called file carving – forensic experts carve the raw data off the disk and reconstruct the files from it. The more fragmented the filesystem, the harder this task become.
Many open source tools automate the carving process: The list is headed by Foremost [3] and its derivative Scalpel [4], but other tools include PhotoRec [5] and FTimes [6]. PhotoRec does not support generic carving for any file type, and FTimes is so hard to use it is not worthwhile for most users.
