Well, as for me, there are better products to choose from. These files can only be previewed after recovery – and you can only recover files after you buy the full version license. When looking through the files, we can see that some of the deleted photos have been recovered, but documents and videos cannot be previewed, and the recovery prospects remain unknown. The user interface is not too convenient, so it can be more difficult for beginners to use this product. It didn’t find anything with quick scan, and with long scan, it uses a signature search algorithm, with file names and structure being lost in the process.
Fortunately, data recovery tools can recognize such devices and restore data from them.įor our tests, we have selected several popular data recovery tools – Hetman Partition Recovery, Reclaime, UFS Explorer, Disk Internals, Diskdrill, and File Scavenger. In Windows, you need a specialized utility or a special driver to view the contents of a removable drive (such as a USB flash drive or an external hard disk) formatted into XFS. In today’s tests, we are going to compare results of searching for data deleted from XFS file system, and we will try to delete some elements of the file system structure to find out how top data recovery tools can cope with the problem. All leaves are located on one level (the lowest one), and every block (unless it is the only root leaf) should be at least half full of keys. In B-trees, keys are combined into blocks containing several of them, which helps to considerably increase their effectiveness on disk storage devices. If some elements of this chain are removed, there are chances that the data recovery tool won’t be able to find the path to your data. That is why the data is stored in its leaves, and in order to access the information, a data recovery tool has to go down the chain of links before restoring any data. Blocks allocated for extension of B-trees.Information on allocated and free inodes.The Allocation Group is divided into four kinds of structures: The Allocation Group zero (together with superblock zero) are located at the beginning of the disk.
Allocation Group structureĪt least the first two kilobytes of every Allocation Group have the same format. The size, number and other characteristics of Allocation Groups are found in the superblock, and this block is located at the beginning of every Allocation Group (just as it is in Ext2).
