For each file it detects using any of the two methods, it checks if it also detected using the other method. Apart from that it also scans for 250 or so file types using a RAW scanner. ReclaiMe is superb when it comes to file system reconstruction. I know of one tool that does this: ReclaiMe File Recovery. So files that were detected file system structures, including their name and directory path should not show up in the RAW file listing. At the same time you do not want duplicate files.

Ideally you’d use a software that does both file system reconstruction and also performs a RAW scan. Data recovery with original file names + RAW the right way … Problem with those is that you can not tell how many of those RAW files were duplicates of the file already detected complete with file names and directory path. Others (better) produced a directory structure and in addition tens of thousands of files were detected using a RAW scan technique. However, a few tools proved that it was possible to reconstruct a more or less complete and coherent directory tree. But those tools were not able to reconstruct the file and directory structure. Many were only able to produce recoverable files based on a RAW scan. I discovered this during my testing of data recovery tools against a fairly complex case. Many mainstream and popular file recovery tools can not handle too complex situations very well. File recovery software falling back to RAW recovery The latter happens more often than you think and you may simply need better software. If the you use software only produces up generic file names (File0067.doc for example) and no directory structure you may be using a RAW file recovery tool, or the software failed to reconstruct the directory structure. Most likely, most files that were found using the file system, are also detected during the RAW scan. In general if the software was able to reconstruct the directory structure, you can ignore this RAW folder. When you expand this folder you’ll find files ordered by file type such as.
Typically apart from the directory structure they create a folder called RAW. The files typically have generic file names with no relevance to the subject photographed and are mostly stored in one folder (DCIM).Īlso, many products that do file system based recovery are also capable of RAW recovery as a kind of fall back mechanism. When recovering digital photos from memory cards original file names or the directory structure are of less importance. Often this type of software is specialized in specific file types, such as digital photos. The latter can not do data recovery with original file names and directory structures. And on the other hand there is software that scans for individual files instead, ignoring the file system. So there is data or file recovery software designed to do recovery based on file system structures. When the footer is reached, the file is closed and saved with a. As soon as a header (a JPEG header for example) is detected, a file is opened and the raw data is dumped to the file.
RAW file recovery or carvingīy RAW recovery we mean the process of software scanning the disk for file headers and footers rather than for file system structures. On an SSD these actions will most likely irreversibly delete the data.Īlthough rare, it is possible that the file system is damaged to such a degree that it can not be reconstructed in which case only RAW recovery is an option. A chain of on disk structures pointing to individual filesĪpart from corruption, user initiated operations such as file deletion of formatting a volume also leave file system structures largely intact on conventional hard disks.
