Had a power cut, needed to update firmware on drive to exit the Emergency mode that the drive went into, as update was completing it asked for Buffalo username and password, which has not been changed from default settings, but it did not like them so refused access so not sure if firmware has worked. Now the drive is saying that it is not mapped, so not allowing me to access shared files, but it shows up as on my network ? any ideas other then put a hammer to it would be greatly helpful.
