(Sony) Memory Stick
Is that what it is, a Sony Memory Stick, a type of memory card, or another brand's clone of that ?
If that's what it is, what are you plugging it into ?
A memory card slot built into the laptop or netbook, or on the front panel of a desktop computer, or a memory card slot in an external memory card reader that plugs into a USB port ?
If the latter, is the external memory card reader plugged into a USB port built into the computer's mboard, or into a USB port in an external multi port USB hub that plugs into one USB port built into the motherboard ?
You are much more likely to have problems if you are plugging the Memory Stick memory card into a slot in an external card reader.
