Subject: [Hampshire] Losing data on iPod
For my birthday, Laura my girlfriend got me an iPod shuffle 2nd
generation thing with the clip on it.

Now, it almost works absolutely fine, except I mysteriously lost a
load of songs from it yesterday. I put this down to it auto-mounting
with the wrong character set.

I'm using Ubuntu Edgy, so I havn't had to alter anything in my fstab.
I believe it's all being handled by Gnome's HAL. Therefore, my
questions are:

1. How is this actually working? I'm just guessing at the moment. I'd
also like to know how it's detecting it's an ipod and coming up with
the nice icon etc.
2. How can I change the charset mount option?

I'd like to keep doing things the HAL way if possible as I think it
seems like the path of least resistance.

Below is some dmesg output:

3. Also, when I was running under the Xen kernel and I unmounted the
device, my computer went funny...like the clock speed had been chopped
in half or something. top and dmesg showed nothing strange. Any ideas?

Linux continues to mysterise me!
