Can I download SureThing Disk Labeler for Linux?
No, you can't use this application on Linux because it hasn't been released to support this platform. According to the only download available through the official website, you can use the software only on Windows operating systems. Of course, you can use an emulation tool called Wine, but it's not guaranteed that it will run the software.
