Hi … I have a problem with My Passport Essentials

I copy any file >100GB would immediately lag … :angry: but if I copy a file <100GB smoothly … :wink:

Thanks … ^ ^

*sorry if my English not good :laughing:

What are the transfer rate that you get when is less and more than 100GB? The type of file that you copy, also affects the transfer rate, for example pictures will take longer than 10GB+ movies.
