    Hi I'm a newbie to this forum so, please accept apologies in
    advance for any posting which is not appropriate.


    Please see attachment for System Profile information. The
    machine has two internal drives; the original Apple included
    250 GB ST3250820AS P and a 500 GB Seagate ST3500320AS
    which I added. The 250 GB boots Tiger which had not been
    used regularly for a while and was patched last Friday to
    10.4.11. It seems like the symptom became worse after the
    patching on the Tiger drive. The 500 GB drive runs Leopard
    which is patched regularly and currently is at 10.5.6.


    Machine particularly after sitting overnight will not boot up.
    Sometimes it makes it to the login prompt sometimes it does not.
    It usually presents itself with an incomplete graphics character
    screen (missing pieces), squiggly changing graphic characters,
    or graphic characters that look similar to a test mode program.

    The same problem can occur during a "wakeup" from sleep mode
    with the machine idle for several minutes. The length of time
    appears to track linearly to the problem.

    I have occasionally allowed the machine to "self heal". After
    20 minutes the machine will eventually come on line usually only
    to repeat the same process during the next boot.


    When this occurs the only way to get the machine back
    on line quickly is to boot Tiger (Command-c) during boot
    and run
    Disk Utility -> Repair disk against the 500 GB drive. I do
    hear disk thrashing while the problem is occurring which led
    me to suspect an unclean shutdown but I believe that the
    thrashing can also occur during a re-indexing operation for
    Spotlight. After the disk repair is completed the OS will come on
    line. When OX 10.5 is online if I remember to run a Disk Repair
    against the 10.4 drive and boot from the 10.4 drive I can reduce
    this startup fiasco.

    Machine Usage: Primarily web cruising, streaming video from
    Television programs (which I'm suspicious may
    have contributed if not caused the problem)
    and Logic Pro.

    Fixes Attempted:

    CTRL-v during startup to look at messages
    Console troubleshooting
    Disk Repair both Permissions and fsck
    Extensive Hardware Diagnostics from Install DVD
    Firmware upgrade on Seagate 500 GB
    Clearing download lists from Firefox (primary browser)
    and Safari
    Zapping PRAM
    Cache removal from Firefox
    Removal of Spotlight Indices sudo mdutil -E /

    System Logs from both OSs are attached.

    I'll crack the case today and see if something is loose but I'm running
    out of options. Thanks for any help.

    Boot using optical drive and see if the problem will come up if you leave it around.

    Could be your harddrive dying.

    Thanks for responding. However, this problem is occurring
    sometimes with both drives which leads me to be suspicious
    of the controller.
