I am having the same problem with my Zyxel NSA 310 NAS drive, auto scan finds the drive but what ever info I enter the drive will not mount, worked fine before the update by entering vers=01 in advance options, but this is not working for me with the latest version.
I Installed version 1.51 and entered my nas details and it mounted first time. It also added the following to the advance options, “ro, dir_mode =07777,file_mode=0777” , I manually entered the same settings in the latest version and it still did not mount. Depending on what I enter i get the red or orange error boxes.
Any one have any ideas, thanks?
