I have FreeAgent GoFlex Net media sharing device on my desktop. I have been successfully using one Seagate GoFlex for Mac drive in this device. I have a Pogoplug icon on my desktop for my Seagate drive and also for "Files Shared with Me.". When I click the Pogo icon, I see the contents of my GoFlex for Mac drive. I recently purchased a second Seagate GoFlex for Mac drive and inserted it in the other slot. The white indicator light is burning. I see the drive when I go online to MyPogoPlug, but I do not know how to get the drive to show up on my desktop so that I can load files onto it. Help appreciated. Thanks. 

p.s. I am having trouble finding documentation for how to use the combination of the FreeAgent GoFlex Net media sharing device, the GoFlex for Mac drives, the PogoPlug Drive software on my iMac, and the PogoPlug website. What is the best place to go to learn how these all work together? It is not intuitive. Thanks.
