Second, I am not sure I understand the judge decision. If the man truly forgot it, or lets say the files on USB got corrupted (can happen) and the password he is giving out does not work, then how can you continue to jail him (for that reason)? Is this something specific to UK, or are similar US cases out there?

I think the law is very vague due to the people writing it now knowing much about it. I imagine they have a use case of this guy and want jail for anything other than seeing some incriminating evidence.
I guess it doesn't help that it turned out he did know the password and it had a load of incriminating stuff on.
