Another favorite, EaseUS, has very good results but doesn’t offer this option. In addition, our program lets you create a disk image and then recover data from there, which is the industry standard for dealing with faulty drives. Successful recovery Yes/No (+/-)Ĭhoosing the right tool for the job is entirely up to you, and there is only one thing we’d like to add – the algorithm used in our product allows to retain the folder structure and file names which makes it easier to search for certain data and saves your time. Hetman Partition Recovery deserves the top position in this benchmark, as it has coped with all tests successfully and was able to recover all the files. On the other hand, EaseUS couldn’t display the contents of 1 document and 1 video file. EaseUS ranks second because it was much better than RStudio, which did well, though it failed to find the disk contents in the last test. There are two tools that have passed all the tests – Hetman Partition Recovery and EaseUS Data Recovery Wizard. Finding the file you need is going to be quite a challenge when there are many of them on the disk. Such type of analysis requires a lot of time and fails to retain the file names and folder structure, which makes searching for specific data more difficult. Most likely, EaseUS uses in-depth analysis when scanning the disk, because the files are sorted into folders by file type. Volume Header Main removed Testing Hetman Partition RecoveryĪfter Volume Header Main is removed, Hetman Partition Recovery displays the disk but without showing its name, and identifies its file system type as NTFS. Now let’s check how it works in practice: erase Volume Header Main. If the entire file system structure is erased but level 0 folders are still there, data recovery is still possible and our program will do its best to display and recover it. Analyzing the storage device sector by sector, the program finds certain byte sequences, skips lost elements of the chain, and represents the data to the user. Hetman Partition Recovery allows us to analyze the disk space with the signature analysis algorithm. In the next part of the test, we’re going to erase main elements of the file system structure, one after another: Volume Header and its copy, all superblocks, and for the final test, we will remove all checkpoints.Įven if all links of the file system structure are erased, out product will find the data, because its algorithm only looks for B tree leaves which contain the information. The program has failed the test as it couldn’t find disk contents, though the company’s website promises full support for ReFS.įrom now on, our test involves only three tools: Hetman Partition Recovery, EaseUS and RStudio. The best solution for such cases should be a specialized data recovery tool. You have to consider the probability of such issues in the future, and get ready with a reliable utility that would be able to fix problems with deleted files. Hence, a file can consist of almost any number of chunks.Īlthough ReFS is characterized by improved security and efficient data storage features, it can’t protect important information entirely from accidental deletion, virus attacks, or other things that may cause a data loss. For files, the identifier is missing but instead, the structure contains all the basic data about the file including the root of the B+ tree and file fragments. For folders, these elements contain the name of the folder as well as the folder identifier in the “Directory” and the structure of the “standard information”. The last elements are directory items’ records. For a folder object, there are three main types of records: a directory descriptor, an index record and a nested object descriptor.įurther in the directory, you can find the so-called index entries: short structures with the data on the elements contained in the folder. The main structural element of the file system is the “Directory” presented in the form of a B+ tree with the key as a number of the folder object. All elements of the file system structure are of single-level type. The main structural elements of the new file system are B+ trees. Resilient File System (aka ReFS), codenamed “Protogon,” is a new Microsoft file system designed to ensure maximum availability of data, effective scalability with large volumes of information at various workloads, and provide data integrity based on better resilience to damage.
