I guess I lost a lot more than 6 karma points! It's 
been two days since my last post and I haven't received
any more responses.

Please permit me to ask if there is anyone reading this
list who has this working. Specifically, the ability
to replace a card of a different size in a card reader
and be able to mount the new card.

If I have violated any Kapu or in any other way did a bad.
let me know and I will strive to do better in the future.
