I'm pretty sure that the program I used is CopyTrans (but I'm not certain).

If you find no joy in the links below, send me a note and on Tuesday I will find out from my friends what program I used.

I suggest using a program that can be placed on the iPod and run from there, thus you won't need to install software on every PC to which you connect. Also, be sure to set you Pod to be used as an external drive (the software instructions should explain how that is easily done). And doing so won't hurt your Pod.
