MiniTool offers a bootable creation CD; however, it is an additional purchase. This software also does not include a disk-imaging tool. Disk image creators are helpful if you need to restore files from a damaged disk. Using the disk imager, you can create a disk image and restore data from the image rather than the original, which is a much safer option.
Most file recovery software struggles with rendering identifiable preview images. We used the file preview option provided by Power Data Recovery to find our lost files. Although this software did not display complete images of our file content, it was able to display a vertical image of the original file name, which we found useful since recovered file names are usually altered, nonsensical strings of characters. We easily found our lost files using this preview option. It was also able to find our lost music album in one folder. However, to restore the entire album, we had to select all associated files, not just one album folder. Nevertheless, the files were kept together and were easily restored.
MiniTool provides one direct technical support option, which is by email. We contacted the company on a Friday afternoon and received an email response within hours, which is excellent. They also post a list of support topics online, and you can contact MiniTool by telephone with sales questions.
