newbie help

hi all - just put my zidoo x9s up. I have a 4tb connected to the sata and I plan on putting another 4tb external into usb 3.0. I would like to know what are my options of moving files from my pc to those storage devices on zidoo. How do i detect the hard drives on my computer so I can transfer them from PC. i'm sure it's been mentioned somewhere but if anybody can help I'd really appreciate it.

thank you!
