You have seen the exact figures above, so choosing the tool to use is entirely up to you. Disk Drill failed the tests because lmost half of the files were not displayed in the preview mode. Summing up, by results of all tests, there are four tools that have passed them – Hetman Partition Recovery, Easeus Data Recovery Wizard, RStudio and UFS Explorer. On the whole, we can say that this tool is a bit worse than RStudio, which failed to find some folders, but was able to preview all files without exception. The program displays the test disk, its name and file system type.

In HFS+, the Volume Header is located in the second sector (from the beginning) and in the second-to-last sector (from the end of the volume), so that’s why we have erased the main header in the second sector at the beginning of the disk, then run the analysis to compare performance of the tools selected for the benchmark. In the following tests, we have erased file system elements, one by one: Volume Header, Alternate Volume Header, Header Node and Index node of the second level. RStudio failed to detect one folder with a file, while DiskDrill and UFSExplorer couldn’t preview certain files. The only downside in EaseUS is that it lacks the quick scan option. Summing up, we can say that the tool has coped with the task partially, as it encountered difficulties in displaying documents.Īfter the first round of testing, the two best tools are Hetman Partition Recovery and EaseUS as they both didn’t have any issues when analysing the test disk. The Catalog File is a B-tree that contains records for all the files and directories stored in the volume. Volume header which is located in the second sector.HFS boot blocks located in sectors 0 and 1.

The following elements are most important for the proper operation of the file system and are of special interest when searching for missing data: To manage the process of data allocation on the disk, HFS+ stores special service information known as metadata. Just as its predecessor, HFS+ uses the so-called B-tree to store a major part of metadata. Journaled operating system keeps a log file (journal) of changes which helps to recover the hard disk quicker after failures, and accelerates the work of Time Machine. HFS+ introduced journaling, which increased reliability of data storage. HFS+ or Mac OS Extended is the update for the previous file system format by Mac OS known as HFS, or Hierarchical File System.
