Good to see I'm not the only one! Buffalo Support claims it's a Mac problem. Have you tried doing the TM Backup from a new user account on your machine? Worth a try, although didn't work for me. Anyhow, I had to take my link station out of my local network to do a firmware upgrade as it wasn't responding to 1.58 and it seems to work now somehow. I have to restart the router before doing a new time machine backup and connect to drive in the finder (just the general share, not any specific folder). As long as I stay connected it does the job automatically. However, it still gives me this wired icon in istat showing me a restricted folder.
