I am having similar issues, dont think it has anything to do with charging or using a ac adapter, but please correct me if im wrong
here's my copy n paste from another forum:
I just got my ipod a few hours ago.
i have the 9c738 serial (week 38)
i have the latest version of itunes.
running windows xp sp2
so i connected the ipod to the computer using the usb cable that comes with it and after i setup the ipod touch i try 2 transfer all my songs from my library to my ipod and it starts like it normally would but then like a minute or two i get two messages, one that says cannot sync and the other says "the disk could not be read from or written from"
soo its taking me about 8 tries just to transfer about 490 songs
ive been to a few other discussion threads and it seems i am not alone
anyone else having this problem???
is there anyway to fix this???? its driving me insane
THANKS
