Thanks Warren, you win the prize for the most detailed answer.
Polytropon gave me the easiest answer if I just want to use the drive
as a simple storage device; however, if at some point I actually want
to go beyond that your answer is what I would require.
Interestingly enough, I searched through the man pages and FreeBSD help
but never came across anything that specifically addressed flash drive.
Perhaps I was just not looking hard enough.
Perhaps, and I know that this will offend some purists, but a nice GUI
that would do what your instructions detail above would be helpful.
There is no way that I am going to remember all of those instructions in
six months time. Just my 2¢.
