I have a netbook and PC.
I sometimes use my netbook to charge my itouch and get the usual message saying do you want to sync and wipe your hard drive. I say no because I just want to charge.
Yet everytime I got back to my PC to sync I get the same message and choose yes and wipe my touch and have to reinstall everything.
Easy answer would be never to charge from my netbook but that's not really a good long term solution.
So what am I doing wrong why does it ask me to wipe my ipod everytime I have charged using my netbook
It takes about 25 mins to reload everything as well
as I can't find the backup
