JUST TO CHARGE A BATTERY

This is absurd! - I had an iPod with a dead battery. A nightmare.

Tried to charge it using USB port on my girlfriend's computer and my music was deleted.... with error an message.

Your computer must be turned on to charge your iPod - not sleep or hibernation.
If your computer is shut down, the lid is closed or it goes into sleep or hibernation mode, the iPod will not charge.
The car must be running in order for the iPod to be charging,
"yes, this is the way to do it, but it's also far to easy to do it the other way. i've erased the music off my iPod enough times to know that iTunes loves to erase. it might even be a badly worded dialogue box, i don't recall. i do know that it should be a lot harder to erase an iPod. "

The first step in transferring music (from iPod to computer) is to purchase a software program that will allow you to do so. .. or under $20.

use the "EJECT" button in iTunes to eject the device, but leave it plugged into the computer.

... just want to make sure I understood correctly, the adapter has not changed going from 4G to 5G and as long as it says that it can accept 110-220 V its fine?

Prevent your iPod from syncing by choosing not to sync if prompted by iTunes.

... my ipod will say that it is charging but when it asks for my password ..... This morning I tried it on another computer, same problem,

... you are just borrowing a few electrons to charge the battery, that's it. So far no problem, at least for what you want to do: charge it. But no. Clicking NO just "disconnects" the iPod (basically make it off-line), and it no longer charges. Is it that difficult to let it charge?

Bottom line - all I want to do is put selected tracks from my CD collection (mostly classical) on my iPod. From the above event, I now see that I need to back these up on another computer. Looks like a BIG project, it should be easy.
