My sister had just turned on the (G5)computer when suddenly, the computer had that message that says to reboot.


We restarted and when we did, the spinny thing under the apple on the white screen spun for some time. Then it showed the above image again after a flash down the screen. Then it shows code in the top left corner. However I looked at text that comes up after a kernal panic and it was similar but there were no words that were the same except for maybe "the" and "mac." At the end of it it tells me the kernel version.

Now, I haven't backed up my G5 in a very very long time. I put in the boot disc and held down c. It came up with an install menu. I didn't want to reinstall so I went to the startup things. Now my question is this. If I go to network startup, will the powerbook see my G5 and will I be able to drag my file over? I also have an external drive that I could hook up. Please help. I have no clue what to do

I'm not sure this is exactly the right thing to do, but I seem to remember being told to do this last time I was in this situation. Restart and hold down Apple-S This will boot into single user mode. I am assuming that you are using Panther or Tiger. When you are prompted type fsck -fy or fsck -y Keep in mind that there is a space before the hyphen. If there is a repair made continue to do this until you get the ok message a couple of times.
Hope this helps

Yes, that is indeed a kernel panic. Almost certainly caused by disk damage from the symptoms. sknapp351's suggestion unfortunately will likely fail, fsck is run automatically at bootup anyway and has failed to solve the problem after several boots. Also, I'd advise using fsck_hfs rather than plain fsck. The last time I tried plain fsck, it didn't know a thing about hfs volumes and always reported an hfs volume as unrepairable. Even if nothing was wrong with it.

DiskWarrior would be the best answer. Failing that, if you want to copy files off to the PowerBook, all you need is a FireWire cable. Connect the two computers, and make sure the PowerBook is on. Then boot the G5 while holding down the 'T' key. The G5 will bypass the normal boot process and come up as a FireWire enclosure. In other words, all the G5's drives will appear to the PowerBook as external FireWire drives.

Please note that assuming the G5's HD is indeed damaged, it may not mount for the PowerBook. But you can try DiskFirstAid from the PowerBook on the drive (which will likely fail to fix it), even if it isn't mounted. Or let DiskWarrior do the repair.
