Can't connect to mybook on mac 10.5 not lion

This is all it does, says connecting forever!  I have reset the unit, I have tried to map it through “connect to server”, it just all of the sudden did this, I have no explanation. PLEASE HELP!!  There are very important pictures and files on this unit that I just cant loose!

Hi there, let’s start from scratch… Can you access the MBW if it’s connected DIRECTLY to the Ethernet port of your computer? ANd can you access it from another computer? Or can you PING it on Network utility for a response?
