disconnect the ipod from your computer, restart the computer and connect the apple usb cable to ANOTHER usb port on your computer and it should work.

restore your ipod, it will solve the problem.
Here is the REAL solution. Ending ipodservice.exe will NOT WORK.

1) Plug your ipod into the computer using firewire or USB.
2) Open MY COMPUTER
3) Wait until the ipod shows up as a drive letter
4) Right click on the ipod drive letter and do a ' quick format ' (Now the ipod is just a plain windows hard drive)
5) When it is complete, run the ipod updater and do a Restore. This puts the ipod software back onto it
6) Remove the ipod from the usb or firewire port, plug it into the wall power supply and allow it to finish the update

If I've helped one person, then I'm happy.

might need new battery

Hi,
If your computer is recognising other ipods and not yours there is a possibility of somethin being wrong with your ipod.You can always get it replaced.Or else maybe you should check the USB cable you are using to conect.
Finally try your ipod on another computer.
This oughta help you arrive at a conclusion.

TRY HERE FOR THE LATEST VERSION OF ITUNES AND IT WILL HAVE THE LATEST DRIVERS FOR YOUR IPOD TOO.

ONCE YOU HAVE DOWNLOADED IT CONNECT YOUR IPOD AND ONCE IT IS RECOGNISED IN ITUNES GO TO THE OPTIONS FOR YOUR IPOD AND RESTORE IT FROM THERE

Hold down the middle and menu buttons at the same time for about 10 seconds. this will restart the ipod.

hope this helps and good lcuk!
