It's a Power PC, so I believe Apple Partition map would be correct.

I tried your suggestion a few time, and it didn't work, that drive just doesn't show up on the option-boot menu. Shows up immediately when connected while another drive is the boot drive, though. And I have a large video file on there, and it plays just fine.

Repaired permissions, used disk utility (showed no problems), zapped the pram, even used DiskWarrior.

It's not a Porsche design drive. It's been my main drive for over a year, always worked. Like I stated, it's not a "crisis", the data is still all there. If I can't get it bootable, I'll just have to figure out how to get my Firefox and Safari bookmarks off of it.

ummm...speaking of journaling, I have journaling turned off. Was turned off when I cloned it, and turned off when I cloned it back after partitioning it. Now you'll probably yell at me and tell me it says somewhere in BIG LETTERS that journaling must be turned on.

At least that's another thing to try.
