If you don't have iTunes installed and you own a scroll wheel or shuffle iPod - you need to set your iPod into "Disk Use Mode". If when starting TouchCopy you get a message indicating that your iPod cannot be found but your iPod is connected it may be that your iPod is not configured for "Disk Use".
Please note that these instructions do not apply for the iPod Touch/iPhone, as iTunes needs to be installed on your computer for TouchCopy to be able to work with these devices.
You can set your iPod to disk use mode without using iTunes. Follow these instructions...
Make sure your iPod is disconnected from your computer.
Reset your iPod by pressing and holding the center key and Menu key. You need to hold these keys down together for about 5 seconds until your iPod resets.
As your iPod resets the Apple logo appears on the screen, press and hold the center key and Play/Pause key together until a check mark appears on the iPod screen. You can now let go of the iPod keys.
Now connect your iPod to your computer.
