"I decided to just copy apps and data via FireWire however ejecting the Ti HD icon failed."
What computer did you have it connected to?
"So, I shut down the laptop and then I had a disaster since now the Ti wont boot. I had partitined my HD into two volumes, one containing the OS (PB Main) and the other a empty working volume. I tried DiskWarrior 3 but it could not see the hard drive OS, that is PB Main."
Did you parttion it using Disk Utility?
If so, the reason that DW can't see one partition is that when you partitioned it, you did not check the little checkbox labelled "Include OS 9 Drivers" for that partition. It's an easy mistake to make--the checkbox is off by default. Fixing this mistake requires reformatting the hard drive.
"I am now in a catch 22 where the laptop appears to have to go back to the factory because I cannot eject the DW 3 disk so that I could reformat the HD with the OS installer!"
To eject the CD on any Mac, turn on the Mac and hold down the mouse button. This works on PowerBooks and iBooks, too.
"If I can get my laptop up and running again, can I transfer files via the ethernet by connecting the laptop to the router?"
Yes. But FireWire is much faster.
You can probably fix the damaged partition by attaching the TiBook to your desktop system by FireWire, then running DW on the FireWire volume. You can't run DW from CD without installing OS 9 drivers, but you *can* run DW from a desktop while the portable is connected via FirewWire (in fact, I just hadd to do this with my iBook this evening, which is why I'm still up at 3 AM).
