I have been a DiskWarrior user since my OS 8-ish days and have always been very happy to use it in emergency situations. DW is IMO a must-have app for any Mac user.
I didn't have any problems (and still don't) with DiskWarrior 3 (rev.39) but it's slow and DiskWarrior 4 promised to be faster so I went ahead and bought it a few months ago.
At first, it was DiskWarrior 4 (rev.41) I got in the mail.
When I tried to boot from the CD, my iMac G5 would instantly kernel panic. I looked at the CD surface and it seemed like the burn surface had circular scratch marks that didn't look anything like what is usually visible on any CD or DVD media I had seen. So I thought it was a defective CD.
After talking with Alsoft Support, I gently washed it to see if it was just dirt of the surface making the Mac kernel panic. Nope, it was not. Then they recommended I burn another copy of the CD in case the copy would work better. Nope, still no joy. I tried unplugging all unnecessary peripherals before booting from the DW CD and again, it kernel panicked.
I then tried the DW disk on our 1 GHz G4 iBook and the iBook could not even see the DiskWarrior CD, even if I tried to load it through Apple's Disk Utility. I was now sure the CD was damaged and asked Alsoft for another DiskWarrior 4 CD to replace this one that didn't work at all.
In the meantime, DiskWarrior 4 had now been updated to rev. 42 which is the version I got a couple of weeks ago.
I tried it and this one makes my iMac kernel panic as well.
I am thinking here that it cannot be a software conflict because I boot from the DW CD and no matter which Startup Items I have installed, these do not interact with the boot up process.
I am thinking it could be a hardware conflict:
- I am using the new Apple Alu wired keyboard and the wireless Mighty Mouse: both did not come with my iMac. I will be trying soon to plug back in the original keyboard (which I absolutely hate) and the Mighty Mouse that came with my Mac in the hope that this would solve the kernel panic problem.
- Another possible culprit is I have third-party RAM installed so this could also be another variable in the equation and I might try pulling the extra stick out to see if the boot up from the DW CD is normal.
Other than that, I am at a loss here. My iMac meets system requirements (both hardware and OS X version - am using OS X Tiger 10.4.11) and cannot see what else could be a cause here.
Alsoft Support, when I first reported the kernel panics with DW (rev. 41) sounded surprised that I had problems, so it would look like this is a very rare occurrence.
Would you guys have any ideas? What do you think about this? Is there anything else I should try?
Thank you for your input. :)
