Our next test was performed on the drive where the files had been deleted, after which we'd formatted the partition. These opened perfectly in Stellar Data Recovery's "Preview" Pane. A total of 37 files were found across 10 folders, including the original 25 deleted files. In the very first test of files that had simply been deleted from a drive, it completed the scan in under 2 seconds. Still, we were very impressed by the low footprint of the most recent version of the utility. This high CPU usage is not unusual for data recovery software, so it's best not to use it alongside other resource-intensive applications. However, it did use 200MB of RAM and approximately 75% CPU. Previously, when we tried Stellar Data Recovery on a Windows 10 laptop with 8GB of RAM and a 1TB hard drive, a quick scan of our hard drive took less than four minutes. However, it did retrieve a lot more data-125GB compared to 88GB with the quick scan. There is also a "deep scan" feature, which we used last time though it consumed significantly more RAM and a similar amount of CPU and took over 12 hours. Stellar Data Recovery: Performanceīoth in October 2022 and when we ran our most recent tests, Stellar Data Recovery's "quick scan" was able to detect lost files in seconds. Still, if you're considering buying software we encourage you to read all reviews thoroughly and make sure that the developer offers a refund policy. We do not believe that running data recovery tools in a virtual environment has a significant effect on how they function. We then checked if the utility could see it and if so, recover the files. The drive didn't mount automatically in File Explorer and showed as being unpartitioned in Windows "Disk Management" utility. Recover corrupted files: We used the freeware program 'Victoria' to overwrite the volume header of the drive containing the files with zeroes. We then tried to recover the files from the formatted partition.ģ. Delete & format: The files were deleted as outlined above and we also performed a 'Quick Format' using the 'Disk Management' utility built into Windows 11. File deletion: the album files were simply deleted from the drive and the Recycle Bin emptied. The tests were performed one after the other on three separate virtual drives:ġ. We copied the files in the music album to a 512MB virtual NTFS-formatted hard drive, which was then attached to the Windows 11 virtual machine. The files also included 2 XML files, a torrent file and an 'SQLite' file containing details of the album. We did this as we wanted to see how the utility performed with a wide variety of files.The album included 4 music files (2 in Mp3 and 2 in FLAC) format, 6 JPG image files of album covers (with thumbnails) and 4 PNG image files. The files we chose for recovery are an album of Mozart's Music available from the Internet Archive. Stellar Data Recovery: How we testedįor our data recovery tests we used a virtual machine with a clean install of Windows 11 with the free version of Stellar Data Recovery.The only third-party tools installed besides the utility itself were VLC Media Player and GIMP. More advanced tools are available with higher-end plans. New file types can be added if necessary, and safe mode can be activated if you’re concerned about security. For example, you can specify exactly what file extensions you’re looking for. Meanwhile, there are numerous advanced options that can be tweaked to optimize performance. In fact, we noticed it was strikingly similar to the interface of another tool we reviewed: Ontrack EasyRecovery. The layout is extremely clear and intuitive. You can also select what drive and location you want to search, further streamlining the process. This is useful if you’re looking for a specific file or file type. On the initial user dashboard, you can select what sort of files (photo, video, etc.) you would like to retrieve. The installer itself weighs in at less than 5MB and it then downloads the remaining files it needs. Installing Stellar Data Recovery in Windows 11 only took us a couple of minutes.
