I have created a folder called Recovery in D:\ drive to use as the destination for recovered files. Step 1: The first step is creating a Recovery location for your data. DOING SO CAN OVERWRITE THE PREVIOUSLY DELETED FILES RESULTING IN CORRUPTED FILE RECOVERY. How to Recover Deleted Files and Folders Using PhotoRec WARNINGĭO NOT STORE THE RESTORED FILES ON THE SAME PARTITION WHOSE FILES YOU ARE RECOVERING. Extract the downloaded TestDisk Zip (.zip file).Download TestDisk from their official download page mentioned below: PhotoRec comes inside the TestDisk Zip file.Thorough Disk Scanning and Data Recovery.PhotoRec Homepage: Benefits of Using PhotoRec Unlike TestDisk, PhotoRec has GUI version of itself called QPhotoRec. In addition, it is also available on all of the operating systems that are supported by TestDisk. Like TestDisk, PhotoRec is also an open-source program, and is distributed under the GNU GPL license. It is a complete data recovery program, which can be used to recover deleted photos, audio, video, documents, and other file types from hard disks, memory cards, CD/DVD, USB drives, and other portable multimedia devices. It may have the word Photo in its title but it does not recover only photos. While TestDisk is focussed on recovering lost data from the whole disk or partitions, PhotoRec is aimed at the recovery of specific files and folders. Recently, the graphical interface QPhotoRec was developed for PhotoRec.PhotoRec is developed by, CGSecurity, the same developers who make TestDisk. TestDisk only works via the command line. Aside from Linux, both tools are available for various BSD versions as well as for Solaris, Mac OS, and Windows. TestDisk can repair the following filesystems: FAT, Btrfs, and HFS+. However, it can also deal with almost 450 different file formats, mainly in the areas of multimedia and office. PhotoRec was developed as recovery software for photos on the internal or the external storage medium for digital cameras. TestDisk is primarily responsible for recovering partitions, partition tables, the Master Boot Record (MBR), and data that have been deleted. This makes sense because PhotoRec is a useful extension for TestDisk, and the two pieces of software are often used in tandem. The software described here usually comes as a double package in most distributions. However, the costs associated with this type of approach are often too high for private users. A lot more can be done in a laboratory setting that offers clean room technology and direct work on the magnetic disk platters. However the more that data is written to the disk – potentially overwriting the disk areas containing the deleted data – the less likely it is that a typical home user with common tools like TestDisk and PhotoRec will be able to recover lost data. (See the box "What Happens When Data Is Deleted?" for more information.)Īt this point, chances for retrieving data are excellent. Instead, the data delete process involves making a change to the first character of a file name thereby causing the data to become invisible in the filesystem. No Overwrites, PleaseĪ basic rule about how data recovery tools work is that deleted data does not disappear completely in the same moment that the delete key gets pressed. However, if the hard drive is no longer accessible, but is still visible from the BIOS, or if a partition or data within a partition have accidentally been deleted, then it is time to use the forensic tools TestDisk and PhotoRec. The Linux Smartmontools can process and interpret the data for signs pointing to wear and tear of the drive. One indicator that can be used to determine the health of a hard drive running under Linux is the hard drive monitoring software S.M.A.R.T. The SSD drives today are different they die quietly. They could then change out the drive before it became inaccessible. Users could therefore sometimes hear clacking noises when a hard drive was nearing the end of its life. Until a few years ago, all hard disks were mechanical. Damage to a hard disk has the habit of occurring quite unexpectedly once symptoms of mechanical fatigue appear. The latter two states occur more frequently than most users would expect. A common saying for hard drives is that they have just three states: empty, full, and damaged. Then, I let TestDisk and PhotoRec show what they could do. To conduct this test, I destroyed a partition table and deleted about 600GB of data.
