Can I access more than one Internal HD

Brand new to equipment (WD TV Live) and community. I love what I have expierenced so far, including wireless access to the "C"drive on my computer. I was wondering if I should be able to access a second 2 T internal hard drive and if yes, how might it be acquired? All of my drives are  formatted as NTFS

thanks for looking

You can access anything that is shared on your network. That means any drive or folder.
