The following is the case and question: I have a linux installation on a 128GB sandisk. When I clone the disk on another 128GB sandisk the UUID stays the same. My first thoughts to detect a clone was to check the UUID but that clearly does not work.
So my question is: How can I detect that the cloned USB is actually a clone? Is there any way to uniquely identify the USB disk device itself given that your booting from it and not inserting it in the USB port of another linux system?
