Both HDDSuperClone (in GUI mode) and HDDSCViewer have the capability of multilingual support, and now come with language packs. When starting either program, you will be presented with a box with two buttons. The top button is to continue to start the program, and the bottom button is to change the language. When you click on the bottom button, a window will open allowing you to choose from a list of language files. Choose your language and click OK. You should get a message that the language was successfully changed. Then click the top continue button to start the program in the new language.
The language packs are created using Google Translate, which may not always be accurate. But I believe it should be good enough to be able to operate the program in another language.
