I have a real and urgent need to unmount a hidden share from my NAS drive... I am using a WD ShareSpace NAS for TimeMachine...following the instructions contained in another thread [see http://forums.macrumors.com/showthread.php?t=1463343 ]I mounted the NAS' hidden share using the following terminal command sudo tmutil setdestination afp://wd_backup:firstname.lastname@example.org/WD_Backup where wd_backup = share's user name, backup = share's password, 192.168.5.150 = NAS' address and WD_Backup = share's name I now need to unmount the drive but can not figure how to do so please help me by providing me with the necessary terminal command to do so [i.e. to be clear, I need / want to unmount the drive so that it DOES NOT appear as a backup device within TimeMachine). Thanks for all your help, Joel PS. Once I have your attention, does anyone know how to access this share on the NAS drive to recover the space with the issue / problem being that it is hidden?
