I know there are A LOT of questions about this floating about but I can't find one that seems to fix my problem.
We have 4 hard drives plugged into a mac mini which is then accessed by three imacs through a server.
A folder on one of the hard drives has suddenly got a red minus sign on it when you try and access it from an imac. On the mac mini it is fine.
On sharing & Permissions is says:
admin: Read & Write
admin (Me): Read & Write
everyone: Read & Write
The mac mini (admin (Me) ) is the 'owner' of the folder.
When I try and add a new user I don't really know what to add. I think the imacs appear as 'unknown user' under sharing in system preferences.
If I get info from one of the imacs
Sharing & Permissions:
(unknown): Read & Write
everyone : Read & Write
If I try and chose a new owner it brings up a box to type in a name but i don't know what to type. I've tried the user name for the imac but it says that it isn't valid.
I have tried dragging the files to a new folder but I still can't access them
Any help would be really appreciated.
Can you add admin R&W on the one that says unknown?
