The good thing about GNU Project apps is that they usually have a lot of resources online… But you have to be willing to invest some time in learning. If this is your first time trying to recover data, we suggest that you watch read a few articles and watch some Ubuntu tutorials on YouTube before jumping in. GNU ddrescue is compatible with various file systems, including NTFS, FAT32, ExFAT, HFS+, ext2, ext3, and ext4.

If your drive has suffered data loss due to severe corruption or other logical damage, its conservative but persistent approach might be your best solution. It then returns to those problematic areas with more aggressive algorithms to restore data. GNU ddrescue recovers your data by copying as much data as it can from the good areas of your disk while taking note of problematic areas. It also doesn't offer much else in terms of recovery techniques, but it still gives a lot for a price tag of $0. However, its user experience leaves much to be desired. GNU ddrescue has perfected a unique data recovery technique that you don't often find in other software (both free and paid) – we'll discuss this further in the Performance section. Despite this obstacle, the program fills a niche with the way it restores data. As such, it will remain free forever while being regularly updated by volunteers around the world. You may end up permanently overwriting data on a completely different disk.Īs we previously mentioned, GNU ddrescue is in official development under the GNU Project. Just make sure you look at the screen closely and select the correct disks and hit the right keys. However, the instructions are fairly straightforward and you can find a lot of guides online (even on the developer's own website).

You can only use your keyboard to highlight and select the appropriate options for the task. Unfortunately, there is no alternative to TestDisk's command line-style interface. However, it works with all major operating systems and file systems, as well as common storage devices like external HDDs, SSDs, memory cards, and more. It's basically a hammer only meant for nails. It can't scan by file signature or use other advanced algorithms that data recovery software usually offers. However, it doesn't offer anything else outside of this feature. It's really good at recovering partitions, which solves data loss caused by a lost or damaged partition. Like PhotoRec, TestDisk is a master of one. You won't find a lot of software like it, especially for free. TestDisk is also a highly specialized tool that can solve a lot of problems as a result of rebuilding partitions. Yet, TestDisk remains one of the most recommended partition recovery tools today. In fact, these tools are a 1-man project and are supported only by a handful of volunteers around the world. As we mentioned in the PhotoRec section, TestDisk is not backed by official development. You can’t sort or preview your data and there are no scan prediction indicators.Īnd due to the nature of its scanning, PhotoRec recovers data in bulk and can’t extract file names and original folder structure. You can only set basic parameters like file system type and recovery destination. This makes it easier to use the program but the interface looks old and has a lot of limitations.

When you download PhotoRec, you also download its GUI version QPhotoRec. It looks awful, but it’s fairly straightforward. You don’t need to type any commands, but you can only use your keyboard to “do stuff” like selecting your partition and initiating the scan. PhotoRec’s original interface visually resembles Windows’s Command Prompt or Mac’s Terminal. It can also scan and recover disk images, which is a feature that not all data recovery software offers. PhotoRec recognizes a little under 500 file extensions (which is a LOT, even compared to premium tools). However, we've confidently stated in the past that PhotoRec's file signature scanning tool can rival even commercial software. It lacks the advanced algorithms and features commonly found in data recovery software, like session management, file previews, and direct RAID support. It doesn’t do a lot but it does file signature scanning exceptionally well, which provides users with massive value. Despite its lack of official development and only having a small number of volunteers updating it, PhotoRec still works with the latest operating systems and modern devices. As we mentioned earlier, PhotoRec is a completely free and open-source disk recovery software.
