Did you partition it "Mac OS Extended Journaled?"

That's a file system format, not a partition format. Partition formats
available from Disk Utility are:
Apple Partition Map
GUID Partition Table
Master Boot Record
You can boot a PPC Mac only from the Apple Partition Map. You can boot an
Intel Mac only from the GUID Partition Table. You can set up a file system
using HFS+, HFS+ Journaled, HFS+ Case Sensitive, HFS+ Case Sensitive
Journaled, UFS, FAT, and FAT32 on any partition map. Note that some file
system options may not be available for certain size drives; volumes smaller
than 2 GB can't be formatted FAT32, volumes larger than 2 GB can't be
formatted FAT, and some restrictions apply to HFS+ Case Sensitive and UFS
volumes.
The above applies only to Disk Utility. There are (or were) other formatting
utlities which may behave differently.

You're right of course; I was trying to simplify the GUI experience a
bit.

Yeah. I hope the OP figured out what was happening. I suspect a partitioning
problem.

Ah... did you just erase the drive, or did you reset the partition? This is
important. If you just erased the drive, your drive could have the old
partition scheme on it. PPC Macs cannot, repeat CAN NOT, boot from a drive
which is partitioned using any partition scheme other than Apple Partition
Map. Intel Macs cannot, repeat, CAN NOT, boot from a drive which is
partitioned using any partition scheme other than GUID Partition Table. Every
single third-party drive I have ever seen ships from the vendor using the
Master Boot Record partition scheme... which _no_ Mac can boot from.

Boot the machine from either the System disc which shipped with the machine
or from an external hard drive, or in Target Disk Mode. If you boot from the
System disc, you can get to Disk Utility using the Install menu. If you boot
from an external disk or in Target Disk Mode, Disk Utility is in the
/Applications/Utilities folder.
Launch Disk Utility.
Click on the drive itself in the left pane in DU. (It should have a name like
'80 GB WD')
Select the Partition pane
Look at the bottom of the window and see which partition scheme is in use. If
you don't see 'Apple Partition Map' you will have to repartition the drive.
Click the 'Option' button, select 'Apple Partition Map' from the dialog which
pops up, click 'Okay', click 'Partition', click 'Partition'.
You have repartitioned your drive, and it should now have the proper
partition map. You have also deleted anything that was on the drive. You will
have to reinstall the OS. If you booted from the System disc, select the
Installer from the Install menu. If you didn't boot from the System disc,
reboot from the System disc. If you don't have a System disc, get one.
