I finally pinpointed and solve the problem I been having with my Memory Stick :DD But not before I spend another 950 baht to trade the copied MS to a real one from SanDisk T^T
I have recalled the last files I add to the last MS the night the problem start. I did not want to believe it caused the problem but it is... I delete the file from MS and now it work like a charm!
I could not believe that the music file, which I made myself by ripping it from a video file, would cause me so much time and money.
