TICKET ARCHIVE -> Invalid B-tree Node Fix
concreteblonde - Aug 8, 2005 - 6:19 am
I found your site from a search on "invalid B-tree node fix 10.3" there was a post with the subject Question - Snow Imac Startup Failure dated Jul 10 2005, 5:15pm. I am having a similar problem.
My set up, I have a G4 iMac (the first 15" flat screen version) 60G HD partition 20G & 40G the 20G partition running the system & apps. and the 40G for file storage. I also a G4 Powerbook both running Panther. I have not switched to Tiger after the problems I had with the first versions of Jaguar & Panther. I do however run and intall software updates. Last but not least I have a USB2/firewire 250G external HD. I use my Powerbook daily (wireless) and don't really use the iMac that often.
About two weeks ago I went online with the iMac and found that I needed to update the software with 2 security updates. Upon restart I was greeted with the spinning circle forever, so I shut it down with the power button. When powered on again, I first had the start up chime which I had disabled I then had a blank grey screen & then a broken folder icon with a flashing question mark. I then booted from the 10.3 intallation disc and ran Disk Utility. It show the entire 60G HD(no partition) but the verify & repair options were grey. The only available function was erase. I had luckily just backed up the 40G partition days before & have all the install discs for the OS & apps. so I tried to run the install disc and there was no drive to install to. I suspected a problem with the security updates(previous external firewire HD fried with an update), after reading Apples site and finding no trace of any similar problems I tried to instal the OS to the external HD and boot from that but it still does not start up. I tried to boot from the Disk Warrior disc & the Tech Tools Pro discs but again no start up.
I today decided to erase. I then had the ability to verify & repair I ran verification and the drive failed verification with the following:"Invalid B-Tree node size", Error: Underlying task reported failure on exit (-9972). I stopped to do some research on the error message "invalid B-tree node". While the Apple site has nothing I found tons of user complaints on the web, most of which did not involve the start up disk until the one I found here. I have not run repair but from what I have read it sounds like it wouldn't help and I don't know if it will make it worse. What do you suggest?
Thanks!,
Tamara

I am using DW 3, Yes I inserted the CD into to the the CD/DVD drive, power off, then power on while holding down the c key. The grey screen with the apple logo and winding circle never stop. I am using Panther 10.3.9.

Tamara, on my olg G3 400 Mhz 380Ram, DW302 takes between 5 to 8 minutes to boot.
You said that you nooted form the 10.3 installation disc and repair.
So i do not see why you cannot boot on DW ???

I can put the DW CD in, hold the c key down, and I have waited 20 minutes and the grey screen with the apple logo and winding circle never stop. If I release the c key after about 10 minutes a blank grey screen appears for about a minute then the blue wallpaper desktop appears completely blank for about 5 minutes then the computer restarts itself and repeats the same process starts over and over and over.

But, you cazn boot normally from the Mac Osx install disc, right ?
How long does it take ?
Which release of DW do you have ? 3.02 ? 3.03 ?
Is the burned surface of the disc dirty, scratched ?
