hardware failure

What is up with all these questions you are asking? You are asking heaps of one line questions, without giving any context about what it is you are trying to do, and without giving any indication of what you have tried so far and why it didn't work.

If you write some clear clarifications about what exactly it is you are trying to achieve I'll be glad to try to help. As it is though I don't see how anyone could give you a decent answer.
