I can't get drive letter access on my Pogoplug attached device.  Is it because I haven't installed the software?  I don't need web access, and I have my own backup, so don't anticipate needing to go through the Pogoplug interface.  All I need from the device is drive letter access from each computer on my home network.  If possible, I would prefer not to clutter up my system with software that I don't need.  Thanks.
