iMac G5 w/10.3 will not boot

I have a iMac G5 with 10.3 installed on it.  As far as I know it was running fine and one day my client went to go boot it and i stops at the gray screen with the spinnnig gear.  I did try starting it in verbose mode and it appears to hang at "Starting kernel event agent".  I don't have any copies of Jaguar so I used a copy of tiger just to see if I could get it to boot.  It did and I was able to run a first aid on the disk just to check if there were problems and it wasn't able to finish because there were errors.  There is data on this drive that I need to get access to.

Help.

Boot in single user mode .. and run fsck -y .. until errors are repaired.

If Disk First Aid finds errors that it cannot fix, you have two options. The first is to purchase and use a higher powered commercial disk repair utility like:

Diskwarrior  http://versiontracker.com/dyn/moreinfo/macosx/19441

or

TechTool Pro  http://versiontracker.com/dyn/moreinfo/macosx/2895

The safest alternative, however, is to forget about repairing the drive and use Data Rescue II to recover the data to another Mac, then scrap or reformat the drive:

Data Rescue II  http://versiontracker.com/dyn/moreinfo/macosx/1133

Alternatively, if you purchase Data Rescue with the option bootable CD, you can recover the data directly to a firewire or USB external.

In any case, your best bet is to stop using the computer altogether until you decide on a recovery strategy and anything you do may make matters worse.

You will have to connect the iMac to a second Mac which has data rescue on it using a firewire cable, then start the iMac in firewire target disk mode

I would try software like Diskwarrior. It is a very powerful disk repair/maintainance tool.

http://www.alsoft.com/DiskWarrior/

You can boot off the CD, and should be able to repair the install of osx.  I have had this happen in the past where this tool has saved me lots of time.

Another method with this tool is if you have it installed on another mac, Attach a firewire cable,boot the broken mac into target disk mode, then use DiskWarrior on the working mac to scan/fix the broken one.

Hope this helps.

Thanks for your help.  We think a like.  I usually don't like to spend a lot of time repairing when data backup and recovery take less time.  Thanks for the tool though it worked great.
