I can see all my drives on the desktop.   I can only see two out of four in System Prefs.   I can see them all in Utility.   I would like to be able at any time to select one of the missing drives in Sys Prefs as the Startup drive.   One of the drives is a 1tb Seagate drive just installed and formatted, and it's never shown in Sys Prefs.   The other one is a drive used for quite some time as my store for FCP stuff and disappeared from Sys Prefs a little while ago without any action on my part that I can recall.   Can anyone suggest what has happened and how to recitfy this?   T.I.A.

    I just connected a HDD to my MBP with three volumes.  In System Preferences>Statup Disk, two of the volumes were displayed.  Both have an OS installed, the third does not.  It suggests that only boot drives will show in System Preferences>Startup Disk.

    I attached a boot HDD (Lion Source) to my Leopard partition of my test MBP and got these results:

    (Rasputin HD is a Snow Leopard volume on the test MBP)


    Then I attached two data only HDDs and got these results:

    Note that neither of them is displayed.  To me the evidence is conclusive.  Perhaps the prior OSs permitted displaying all HDDs.
