I have a Sony 128 mb memory stick. I used to just stick it into the USB connection in any computer and it would open up automatically. Now when I put it into a computer the computer sais that it found new hardware and that it is ready to use and a little icon to safely remove the hardware comes up and the green light on the memory stick is even blinking. However it does not open up on its own and when i go to my computer to open it up theres only one possible thing that it could be and it sais removable disk (E. When I click on this one it asks me to insert a disk into drive E or something about how it isnt valid. When i look at the information for the driver it tells me that everything is working fine. is my memory stick just no good anymore or am i doing something wrong?
