I believe I figured out my issues with the USB drive, and your first question is at the heart of the issue. The embedded OS that runs the LinkStation I believe is some form of Linux. The USB drive is formatted NTFS, I have been using Open Suse 11 for so long now I ha forgotten the many, if not most, earlier version of the Linux kernel will mount a NTFS volume just fine however mount it read only. So I will, and at this writing have, copied my music to the internal drive, and will not go about formatting the USB to XFS or ext3 or a more acceptable format.
