Try this: if your card is in one of the three lower slots (assuming the 
S900 has the same orientation as a 9600), then try it in the top three 
slots and see if the problem still happens.

If the problem goes away, then there are a few other problems to discuss. 
If not, well, not sure what to tell you.
