ioata controller blocking bus
Has anyone else experienced a G4 QuickSilver gradually failing? A friend complained about hers not booting, partially booting or getting past login and then hanging.
I took a look at it last night, and the only useful info I could gather was while running fsck in single-user mode: the repeated error "ioata controller blocking bus".
Over the course of two hours we tried 15 or 20 restarts and/or resets. On most occasions we only got as far as the grey sunshine screen. On the two times we got to login, there were disturbing squeaks/grating noises from the hard drive. After logging in, we got a SBOD within 10 minutes.
The box wouldn't boot from an authorised Tiger install CD (yes, CD) in either the internal or an external drive. It wouldn't boot from a bootable FireWire drive. Starting up with alt held down got us to the blue "select startup disk" screen, but no disks were shown as being available.
I tried all I could think of - repaired permissions one one of the occasions we did get logged in, reset PRAM, reseated RAM. The original hardware test CD reported no errors. Eventually I gave up.
Having Googled the "ioata controller" error, I'm pretty sure that the hard drive is failing. My friend is going to take her G4 to the local Mac authorised dealer, but she's concerned about losing photos and music (whoops, no backup...).
Just wondered if anyone has been here before and managed to get their data back, or had any other ideas?
Thanks,
