I left my tower on yesterday and went to work. When I came home I tried shaking the mouse and tapping the keyboard and it would not wake up from sleep.  I did numerous restarts etc to no avail.  I then did Target mode to my MacBook Pro and it recognized all the drives.  I ran Disk Utility and half way thru got an Invalid Sibling Link error.  Tried to repair that with Disk Utility again to no avail.  I researched and everyone is saying to run a fsck or use Disk Utility from the Installation disks but I cannot get the tray open. While Target mode works when I press the T down nothing else does on the keyboard.  Can anyone help, PLEASE?  I took the precaution of once having the tower in Target mode dragging my Users folder over to the MacBook as a backup but would prefer to get that drive up and running to at least do a back up and restore from it.  Thank you in advance for any advice.

    Pull drives if needed.

    Install OS X on a new drive, this could be a small 30GB partition for emergency only.

    Buy Alsoft Disk Warrior.

    Start making 2-3 backup sets for your drives. Clone and TimeMachine. SuperDuper and CCC are popular for cloning,.


    A FW case that you can put your problem drives in - so you can turn on and mount after the system is up and running.


    As for optical drive door - Option and holding mouse down usually work.

    Do you have backups of all the data on the drive that you want to keep? If so, erase it and restore from backup; do not use Disk Warrior.


    If you don't have backups, I have no recommendation.
