I'm experiencing a frustrating problem with my G4 Sawtooth system...
When I perform a warm reset (ie - selecting restart from the menu or hitting the front panel button), I get a flashing question mark when the system comes back up. On most resets my drives will spin down but won't spin back up when the system restarts. Whether they do or not, still no system folder found.
If I power-off the system, the drives spin up and behave normally.
I had previously been experiencing some disk problems in OS 9, and once or twice had the reset problem, but it's recently escalated to every restart.
I've tried the usual suspects, attempting to eliminate as much as possible:
- switching power supplies
- using different hard drives
- resetting PRAM and cuda
- resetting to defaults in OF
- switching cables so the drive(s) are on the other IDE bus
- switching ide cables
- removing the logic board from the case
The drives work just fine in my B&W: same combination, master/slave settings and same cable.
I've air-cleaned the logic board and processor. It's looking more and more like the logic board's IDE controller is the problem, but since I've had strange quirks in my other G3/G4 machines, thought perhaps someone else has been through this.
