OK, that makes more sense. Your preset files were lost when you reformatted the hard drive without backups of the presets. Since you have the preset results in your catalog, you can recreate the preset files by: Open an image in the Develop module. In the edit history, select the entry that applied the preset. In the Preset panel, create a new preset using the "current settings". After you have recreated the preset files, that the preset folder tree to the backup commands you use. You already have your images being backed up, right? Note: besides the Develop presets, there are export preset, import presets, adjustment presets.... All need to have backups done.
