Can't Erase an old Mac USB Drive
I have an old Mac USB Drive, that contains Mac OS X Snow Leopard, since I won't use it anymore as a recovery backup. I want to reuse it and erase the content and re-format, that should be easy, hey! but not that easy.
This is the Get Info:
How do I solve this problem? Thank you very much in advance
Cheers
