Hello, I bought a 16gb usb flash drive about a week ago so i could use it for movies on my ps3. It was all working great however I noticed that after I used it in the ps3, I could no longer load videos on it (they would go on, they just wouldnt work).. So since this was a new drive I figured maybe i just needed to format it. I used the disk utility but i cant remember which setting i used to erase it. Once I erased it I successfully put a video on and put it into my ps3 to try. The ps3 couldnt see the usb drive anymore. so I put it back into the mac. and now the mac wont see it anymore. I tried putting it into a pc with vista, it recognized it but wouldnt let me format it or open it. Any suggestions?
