I have just bought an Airport Extreme, and it works just fine. Except for one thing. It will not let me access my external Lacie 250 GB HD... It finds it, and then asks for password. When I enter the (correct) password, however, it refuses to let me in. The message I get is something like "unknown user, unknown password or deactivated login". I am a bit desperate, since I have found NO solution to it - and since I know that the password is correct. Any thoughts are very much appreciated! Thanks in advance.
