Ls: cannot access 'SeaDrive': Permission denied in Ubuntu

I am trying to mount a pro SeaDrive to an Ubuntu box. Everything seems to be working (including browsing the directory with Nautilus) but command line ls gives:

$ ls -l
ls: cannot access 'SeaDrive': Permission denied
total ....
....
d?????????   ? ?      ?              ?            ?  SeaDrive
....

Any suggestions?

And without doing anything (…I think…???), it works now without a problem. Huh…looks bit unstable…
