I had to completely reinstall the software on my Windows 7 pc this weekend following a MS update. Thankfully, I had made reinstall discs when I bought the pc. I just plugged in the iPad 2 and was told that it could not read the contents but that I could reinstall the iPad OS, which would wipe out everything on it. Is this needed for the iPad operates fine and all of the tunes are recognized by hype pc on the iPad and presumably they and all of the Notes and mail and apps are saved to the iCloud? Thanks to all.
