drives are not mounting to desktop on macbook pro.
External USB drives, SD cards and even DVD media is not mounting to desktop when connected.
This is a new problem for me and have not had this issue previously. I have successfully connected the same devices in the past.
They all show up in the disc utility as connected. I am unable to mount them from disc utility (this button is disabled) and they are not showing up in Finder either.
Please help!
MacBook Pro, Mac OS X (10.6.7)
