Two days after last update (10.3.0) (coincidence I hope), I found my Quicksilver 2K2 had locked up. When I rebooted it, I was missing my entire 2nd ATA Channel (Secondary). I had a DVD-RW (DVR-106 or 7 @ 10 mos old) and a 25MB ZIP drive on it. I have searched for topics

I've tried:

Reset Firmware
Reset PRAM
Used different cable
Used different power suppy cables
Removed battery
Changed jumpers
Changed jumper position
Repaired Permissions (found some CD-9660 errors)
Repaired Disk (no errors)

I'm left with the conclusion that somehow my 2nd ATA channel has died.

Any other ideas?

TIA!

Boot from the OSX Install disk, see if Disk Utility can see anything on the other bus. If it does, then it's your OS install that's the problem.

Disconnect the drives on the missing bus, one at a time. I've heard of cases where a HD went bad, and pulled the entire bus down until it was disconnected.

Could be a hard failure. The OS upgrade timing was just coincidence.

Murphys law dictates that most odd critical failures will happen when you are changing something unrelated. (New OS install somehow causes hard failure of ATA bus?)
The Disk utility option sounds like the best chance to figure that out.

Ironically, I'm installing 10.4 on my room mates computer, B&W 300 Rev A, with installed ATA-66 Card. Booted 10.3 fine for a year off the card, installed 10.4. Now only boots off other drive (on the PCI cards other bus) into OS9. I can't for the life of me get it to boot into 10.4. And yes, OS 9 sees the other drive with X on it just fine.

It was the Bus. I purchased a Sonnet ATA133 card, plugged it in, connected the cable to the DVD and ZIP drive and Voila! DVD and Zip drive are alive. So definately points towards dead bus.

As a last resort, used the cable that came with the ATA card connected to the Bus..just in case. No joy. That is one dead Bus.

Weird thing tho. DVD playback through the Sonnet card is choppy - both audio and video. I have a QS2K2 @ 933, 1.5GB RAM and a 128MB Radeon 9800 Pro. Sonnet didn't know why the playback/audio would be choppy either.

Any ideas on this new wrinkle?
