Grant,
"Only when you start to use them do you begin to notice more than a casual amount of crashes, lock-ups, and eventually, data corruption. An 80 GB hard drive should be recognized immediately if it is correctly cabled and the straps are set correctly. Both 80 GB and 40 GB drives may be encountering corruption problems on the built-in controller."
The 40 GB drive has been in this machine for at least 4 years. It was originally my machine given me by a Mac Genius buddy. I used it for over a year before I bought my G4. I then loaned the B&W to my cousin who used it for over 2 years before HE bought a G4 and returned the G3 to me.
When I installed the 80 Gig drive (which already had 10.3 installed), the machine would not boot from it. I booted from the Tiger install DVD and tried to install Tiger. The installation got all the way to the end, then the installation seemed to stop. I left the machine sit for about an hour, then heard the boot tone of the machine re-starting. It never booted, though. I got the gray Apple screen and could actually hear the "Welcome to Tiger" music coming from the speaker, but the gray Apple screen never went away.
I tried re-jumpering the drive, thinking I had gotten the jumper opposite of what it should be, but that didn't do any good either. I tried putting the drive in my Granite Digital external Firewire HDD casing, but the drive would never mount on my G4. So, I re-re-jumpered the drive back to the way I originally had it jumpered. It mounted on my G4 just fine at that point. So, I then installed Tiger via the external Firewire casing using my G4 tower. Tiger installed successfully, and I put the HDD back into the G3, but it STILL would not boot. It would never get past the gray Apple screen, or the machine would kernel panic if it did.
So finally, in desparation, I put the old 40 Gig that was in the machine when my cousin shipped it back to me, back into the G3 and it booted from it just fine. I later did a clean install of Tiger, and the machine still boots fine.
So, as you can see, it really seems that the ATA controller chip does not like the 80 Gig drive.
"Why not broaden your options with an external modem?"
I may indeed decide to go with the Apple external USB, but was told by a Specialist at the Apple Store that the new Apple USB modem might not work with the G3. My friend, whose parents I am setting the G3 up for, owns a MacBook Pro, so he can use the Apple USB if it does not work with the G3 and when and if his parents get broadband.
I still would like to know if a PCI based modem will work with the the G3. I found a post on this board late last night (after I posted this thread) where a user had a question similar to mine. He/she was trying to swap a PCI modem between a PC and a B&W. Whoever responded to the post stated that the B&W will not support ANY PCI based modems. It will only support the OEM Apple modem that plugs into the logic board near the USB and Firewire ports or an external USB modem (similar to, but not specifially the Apple USB modem).
Thanks,
Thomas
