My passport (sd card issues)

Hello, I am using the My Passport wireless.
I have tried inserting multiple SD cards, With the auto import setting ticked.
The activity light flashes for about 3 seconds then stops, and no files are imported.

Which version of MPW are you using – the original or the Pro version?

Also. suggest you look into the complete user manual for your particular MPW and see if there is something you are not doing that you should be doing to get this to work.
