    Here is what happens...

    Say I plug it in so no sleep occurs (energy saver settings to no sleep when on power cord), and leave the computer on overnight (screen saver on or just sleeping screen, doesn't matter) perhaps to run a task or not.

    What happens in the morning is that the computer tried to shut down, reboot, log out, or whatever because I have all kinds of warnings and stuff indicating that possible the computer wanted to shut down, but couldn't because of some open program. If no program was open when I left it overnight, then I would get the login screen as though I restarted the computer.

    Well, this of course causes major problems if you are trying to run something like a DOD swipe of a hard drive that takes 24 hours or anything that takes more than a couple hours.

    Technical support (I have only had this 2009 model MB Pro for a month) was helpful and checked permissions upon booting (not after booted and this makes a difference although it didn't fix the problem).

    I ended up having to backup everything (which I already had from Time Machine) and reinstall Mac OS X as an erase and install. This fixed it.

    I had all kinds of permission problems that were not being fixed by Disk Utility and that was probably caused by some cleaner programs like MacCleanse, etc... that really do a good job swiping, but perhaps too good of a job. This is just a guess.

    I fortunately was able to skip installing a bunch of programs I don't use (e.g. iPhoto, etc...) this time and have a bit leaner machine.

    We are good now, but wanted to share this that if your machine is arbitrarily trying to restart after sitting for a spell (assuming you are on the cord power), then you likely will have to erase and install.

    Although Mac OS doesn't fragment files, it sure has problems with permissions etc. sometimes...
    I'm glad you fixed your problem. Thank goodness for Time Machine, eh? It's saved me on several occasions, despite the restores taking hours... :rolleyes:

    Actually, since I purchased a couple 1.5 TB drives from Other World Computing rated at 7200 32MB cache and eSATA connected through a Sonnettech Express Card/34, I get about 1 Gig of data transfer between these two drives every 10 seconds (or 100 MB/second) (one is primary, the other is a time machine backup); therefore, about 45 minutes to move 275 GBs (give or take) of data to restore.

    No bad to me since you can do other things in the mean time and doesn't slow the transfer, as long as you are not taxing the drives during tranfer.
