I recently bought a 16GB Memory Stick Pro Duo from eBay and I'm really excited about it. Now I can hold many songs and videos in to my PSP. However, after playing around with it for five minutes, my Memory Stick suddenly stops working. I was able to put some media into the card but after just barely a few minutes, the PSP can't recognize the memory stick. I thought maybe it has something to do with my portable system but when I plugged in my old 2GB Memory Stick, the PSP can read that one instead. Uh oh. Looks like my brand new memory stick is faulty. Guess I have to get a refund.

Here's another problem. I can't contact the seller. He did reply to my email but I couldn't understand a word he said because of his "Engrish" (He's from China, BTW). I then wrote to him asking to explain it the solution in more detail on how does this refund thing works and how do I get my money back. He still hasn't replied. Crap! Looks like I'm stuck with this broken Memory Stick.
