When I try to restore, I get message:

Could not validate source - Operation not supported

haven't seen anything like this on the web

Could you elaborate on how are you doing it? – Thecafremo May 17 '12 at 8:20

As the message says, it can't validate the source, meaning that either you are poiting to a wrong file (such as an alias, por instance) or the image you are trying to restore is corrupted.

Indeed, the USB stick is irrelevant to this question, the problem lies squarely with the media/image you are choosing to restore from – stuffe May 17 '12 at 12:04
