Hi techno pros could someone please tell me why my ipod nano keeps telling me not to disconnect from my computer even though it has updated everything I m scared to disconnect thanks

Because it's working as a removable disk drive.

If you properly 'eject' the iPod, it'll be fine.

This is normal.

Thanks telly man I m utterly hopeless

It's to stop you disconnecting mid-way through a transfer of data of any sort and causing a corruption of said data. Although you may have actually finished doing whatever you're doing it's always wise to disconnect it via the computer properly just to be safe as it were.
