Instead, it marks the clusters occupied by that file as free space.
Whether these clusters were overwritten with other filesįor the sake of performance, the filesystem doesn’t wipe out a deleted file right away. Whether the filesystem contains information on the clusters where the files were stored. The ability to recover deleted files depends on two factors: In some cases, lost files can be recovered only fragmentarily. The possibility of fully recovering such files depends on the significance of directory entry corruption. 
To recover lost or damaged files due to missing or corrupt directory entries. The data carving technique can be used in two scenarios: In this case, data carving is the only way to effectively recover data. While the system treats both of these types of spaces as free space, partitions of the second type may still contain some file data even though there’s no metadata that can be used to find file locations. Reused disk space - Empty space within a new partition that was previously used by another partition. Unused disk space - Space that was left empty when a new partition was created on a drive. How does data carving work? Data carving interacts with two types of unallocated drive spaces: Data carving allows for detecting and recovering files and other objects based on filesystem contents rather than a filesystem’s metadata and file structure. What is data carving? Data carving or file carving is a forensic method used for reassembling files in unallocated space. Getting a File System Image and Recovering Deleted Data Recovering files with data carving If this information is unavailable, the file is called an orphan. Each filesystem has its own rules for organizing partition space to store different objects (files, folders, symbolic links, etc.).įilesystem metadata may also contain the deleted file’s name and information about the folder this file was stored in. This partitioning information gives you an understanding of the amount of data in the drive image that should be treated as a single filesystem.Ī filesystem is responsible for storing data in a structured way so that each file can easily be identified and retrieved. 
The system stores all information about the location and size of each partition in a partition table. Usually, these partitions are created, resized, or deleted when installing an operating system. A drive usually has several partitions - regions that can be managed separately and are treated by the system as distinct logical disks. Knowledge of a disk’s structure is a must for successfully recovering data from a disk image.

Lost or deleted data can be recovered from a corrupted drive in two ways: physically or logically. Or if a flash drive controller’s settings were reset, the drive simply won’t know what the size of a particular memory sector was or how many sectors the drive had.

Data recovery may be partial or even impossible if the data was corrupted due to the malfunctioning of the target device.Įven if the data is intact, recovering it in full may still be impossible if you have no information on the drive’s specifications. There are many potential risks and issues you should be ready to deal with.
