went to www.ephpod.com
and got free trial of MUSIC RESCUE from the forum after spending most of the day reading threads (wanted to be sure the "trial offer" didn't sting me half-way through a 20 gig download.)
The ephpod's software is the easiest to find, but one of the threads said his new 80gig classic ipod (same as mine!) crashed.
Somewhere there's an ipod compatibility chart, make sure your ipod matches.
There's several different software packages available, with "limited features" but music rescuer offered full features except for annoying pop-ups. Every 50 tunes it said to make this annoyance stop simply donate 10 pounds (british.) i clicked the mouse alot more than 40x finding this!
Anyway, download the help screen also (read it twice!), and it's basically idiot proof.
There's also a book, How to do everything with yout ipod and itunes by Guy Hart-Davis published by McGraw-Hill/Osbourne, that's basically an IPOD for DUMMIES
