However, if you only want the best outcomes, you can also employ Wondershare Recoverit Linux Data Recovery. That's all! You now understand how to use PhotoRec to recover deleted files or data from your computer or external hard drive. You can restore all of the files still on your hard disk once the process is complete. The necessary file can then be restored after sorting through the files. The tool will return all detected files and save them in a folder because it cannot search for a specific file. PhotoRec starts the data recovery process by seeking neighboring data blocks and reconstructing the meta once it determines the data size and confirms that the hard disk and data are intact (not defragmented or overwritten). PhotoRec analyzes data sectors on the hard disk, similar to other file recovery programs, to determine the extent of the data. The recovery tools recreate the metadata once all the linked blocks have been located.Īnd that's how you can get a deleted file back. They locate associated blocks by reading the hard drive sectors and blocks one at a time. The tools' task is to make the metadata accessible for the operating system to read since only the metadata is lost. The role of recovery tools is at play here. As a result of the file's missing metadata, the operating system no longer recognizes it and views the blocks as available for writing new data. Nevertheless, the first block of a file (which contains the metadata) is removed when it is erased. ![]() The hard drive's writing speed is used to write each data block one at a time. Typically, the metadata for the file in question is contained in the first block. Each block has a portion of the data in it. Have you ever noticed that saving a file to a hard drive takes time while removing it is instantaneous? Let's start by understanding that.ĭata is kept in blocks when it is stored on a hard drive. Bonus Tips - How Does Data Recovery Work? Why Can Deleted Files Be Recovered? PhotoRec is compatible with the following Linux operating systems:įor macOS X 10.10 or later Part 5. Each block is compared to a signature database included with the program and has expanded throughout PhotoRec's development regarding the types of files it can recover. After determining the block size, PhotoRec reads the media block by block. ![]() Otherwise, PhotoRec scans the media sector by sector while looking for the first ten files, using the locations of those files to determine the block/cluster size. If the file system is not damaged, this value can be read from the superblock or volume boot record. PhotoRec for Linux first tries to determine the data block size to recover these deleted files. It indicates that the information is still on the file system until some or all of it is replaced by new file information. When a file is deleted, the metadata associated with that file is erased. In an ext3/ext4 file system, for example, the names of deleted files remain, but the place of the first data block has vanished. Because the seek time of mechanical drives is essential for writing and reading data to/from a hard disk, it is critical to keep fragmentation to a minimum. Most operating systems attempt to store data contiguously to minimize data fragmentation. After being initialized during file system formatting, the cluster or block size remains constant at various sectors. Functions of PhotoRec for Linuxįiles are stored in data blocks, also called clusters, under Windows. PhotoRec uses read-only access to the drive or memory card from which you are about to recover lost data for added security. PhotoRec is a companion application to TestDisk, which is used to recover lost partitions on a wide range of file systems and to make non-bootable disks bootable again. PhotoRec for Linux is a free multi-platform open-source application distributed under the GNU General Public License.
