I'm stumped. I have an older iMac G5 (1.8) running OS-X 10.5. It was working fine until I rebooted today. Now it stops at the "Apple" screen and there's no spinning wheel. I booted off of CD, did a Disk Check, repaired some permissions, but no success. When I go to target mode, I can fully access the hard drive. I've even reset the PRAM a couple of times with good strong "bongs". Still no luck. Booting off of CD seems to indicated basic hardware is good but what else can I do to verify the Hard Drive is the culprit or am I missing something?

(Good news is my Time Machine backup worked perfectly and now my MacBook Pro is fully up-to-speed to my iMac).

I wide open to suggestions.

You could do an archive and install on the iMac. What is the S.M.A.R.T status of your hard drive?

S.M.A.R.T. status is "verified". Everything else seems fine.

Maybe the best is to do an archive and install. This is the original drive and the machine is almost 4 years old. Thanks for the suggestions but I'm still wondering "what the heck" happened.

Thanks, Seanc.

Try booting in single user mode (Apple+Option+S I think?) and see what happens.

I tried the archive and install. It went through the entire process and then hung again on reboot.

I then tried the single user and no luck. When I did another permissions check/repair, it said there were a bunch of permissions that had changed and could not be repaired (user/bin/....)

So....I did a complete erase of the hard drive, reformatting, clean install of Leopard, and a restore from Time Machine. All is very stable now as I'll see how it goes for the next week or so.

I'm guessing there was either a flaw in the HD which caused these errors or a "bug" of some sort. I started having problems when I was installing Adobe 8 Acrobat reader and it gave me all sorts of errors.

Anyway, it seems to be fine for now but I'm still quite curious...
