Hi, I have the 1.25G 15" powerbook.
It recently started freezing up, and sometimes not booting.
when it wouldn't boot I would have to use a cd and startup disk to select the drive again. I looked in the log and saw a lot of "I/O error" messages, occuring at the times when the machine would hang.
So, i thought it was the drive. I replaced the drive with a new one, and I had the same problems, with increasing frequency, until I can no longer access the drive.
I purchased a firewire case for the original drive, and ran the laptop off of it for several days just to prove that even the original drive wasn't bad. I even did continuous filesystem copies for 24 hours. It continued to work just fine.
Does this mean my ide controller, and therefore my logic board is bad? How would I confirm the problem, and do I have any other options besides an ~$800.00 logic board?
thanks.
