I have recently bought an iPod touch and it doesn't show up in Itunes (PC). I have looked around on google for people with related problems and found that their solutions for problems similar to mine do not work. I have tried Xplay (doesn't show up), I've gone to the apple website and troubleshooted my iPod (no solution) but I have recently connected it to my friends Mac and my ipod shows up normally in Itunes. Do you think it's Mac formatted, if it is then how do I reformat it to Windows or is there another solution you can suggest?

If it worked on your friends computer it is probably your computer. Check your drivers for any problems and troubleshoot.
