Yes, I have run disk utility, no it did nothing. I have a new MacMini running 10.8 on OS SSD. I have two externals, lets call HHD1 and HHD2. HHD2 is dying so yesterday I was trying to rescue its contents by dragging them to HHD1 except I kept getting an error the operation wasn't allowed because I didn't have permission with some of the items (this would happen with each individual item as well). I found a way around this by using Carbon Copy Cloner to move the files over--success. I let it run overnight. This morning I download VLC for myself but got the same permission error when dragging the program from the DMG to my applications this time on my OS SSD (the problem has spread somehow after my success with CCC). As far as permissions, I don't see anything that doesn't give me (administrator) read and write. Users is read and write too, Everyone else is set to read but I thought that's okay. This actually happened to me years ago with Leopard and I thought I had to use a tool to correct permissions in a volume. Any ideas?
