So luckily, this doesn't pertain to my main Computer (mac pro) but it is still greatly annoying me as I cannot figure it out! So I'm setting up my old PowerMac G4 MDD as a second computer in the house and I went to change the permissions of my 2nd internal drive (it is used only for storing media files) so that only I could see it and not any of the other users. I have successfully done this before in the past but I must have messed up somehow because now it does not show up on the desktop or anywhere else in the finder. It does show up as mounted in disk utility and everything is OK after verification. My startup drive is just fine and shows up (Macintosh HD) but my backup drive (Macintosh HD 2) does not. I've tried various terminal commands that have worked for people with similar problems but none have worked. Most of the commands were for those with external drives. Can anyone help suggest anything? I'm stumped as to what to do!
