LaCie MiniHD connect network problem

I have a LaCie MiniHD connect in my local network. Did everything LaCie told me to do so I could write to the USB attached LaCie drive.
Formatted the drive in OS X EXtended but not journalized.
Tried to connect via smb://MiniHD. smb.tcp.local and the network told me to enter my ID and Password, I don't know why.

So I brought back the disk drive to my mac and changed the whole drive permission to read and write for everyone.

Brought back the drive to my TV and now I could transfer anything from my mac to the drive.

I was glad of that, but having shut down the drive and the MiniHD connect, when I opened it again to transfer something from my mac to the drive, I still got the same problem again with the same message.
"One or more elements cannot be copied to "LaCie_750" because you don't have the permission to read. Do you want to copy the elements you are authorized to read."

I suspect the software on the Lacie MiniHD connect to block OS X when it initialises the drive on startup.

In particular I see a folder named _HF2VN~W appearing in the root level of the drive.

Can any one help me with thi samba network problem on Mac OX 10.6.5?
