Well what happens to me is that its idle for 20 seconds and only then it is
mounted, and spitting out the same error to console and /var/log/messages. 

Was the disk fully scanned when you try to mount it? Cause it is fine for me 
when it was scanned fully.

So its "not only me" thingy, most people should experience this (giving that
I'm the third person to report this).
