Update. I've again done a full duplication of the source disk to the target disk and have had the same result. Everything copies successfully, but the disk can't be set as the startup disk. Same error as before:

"Can't find IOService for disk1s9"

. Strange thing is the target disk is actually /dev/disk1s10

As noted above, a fresh Tiger install worked flawlessly.

Here's the setup of the disk:

Source disk: 40GB 1 partition. (/dev/disk0)
Dest. disk: 120GB 2 partitions:

1. 80GB Case-sensitive journaled HFS+ at /dev/disk1s10
2. 30GB Journaled HFS+ at /dev/disk1s12 (Will be an OS9 part.)

Any ideas are greatly appreciated!
