David, I would suggest an archive and re-install using the system DVD that came with your computer, then update in steps to your current system level using Software Update (or alternatively use the .dmg of the 10.4.8 combo update that you hopefully saved for such an emergency following your last system update). If your firewire drives do not appear as expected after this step I would proceed to test all of your hardware using the latest version (4.04) of TechTool Pro. A failure of your firewire ports (this can happen) would lead me to purchase an inexpensive firewire PCI card as a work-around. Macsales.com has them. Best wishes for your success, J H H On Oct 20, 2006, at 8:20 PM, David Ferleger wrote: Need help ASAP! Using MacBook Pro 17" with OS 10.4.8. Disk permissions are OK. And (at least before just now) Disk Utility REPAIR from a second computer showed it OK (after repairing a minor volume info file). After that Disk Utility repair with the 17" as Target Drive, I left and returned 1 1/2 hrs later. 17" had not been plugged in. Started up. Battery was Zero. Booted up fine with AC charger. THEN..... 1. external LaCie HD plugged in by either Firewire 400 or 800, DID NOT SHOW ON DESKTOP, though I can feel the vibrations of the disk when touching it. 2. Disk Utility FREEZES without showing ANY disks existing. Have to Force Quit to leave it. 3. System Profiler shows my computer data, BUT the Firewire selection, also Freezes, showing nothing, and have to Force Quit System Profiler too. 4. Email and internet work fine. Answer here or privately.
