but at the top it has no name and the only option it gives me is to format

managaer but i can not access it, and the only option it gives me is to format the drive

Windows will not work with Mac Formatted drives

You will need to format the drive to work on Windows

Or, you can use HFS Explorer to read and write to the drive
