Now that I have a rev. 1 b&w g3 I am learning fast its faults. I am constantly having problems with it. Freezes, panics, question mark folders, broken folders, and stalled booting. I have been up late several nights checking hardware and software and have finally come to a conclusion. Its the ata bus. I knew it could not handle 2 drives but didn't know it would choke and constantly corrupt with a ultra ata 7200. I read this at Apple and XLR8, and after everything else, it must be the cause. Well that is unfortunate because I was not given its origianl drive (which is now marginal anyway), so I must forgo my initial mods to buy the ata pci card. Bummer...well unless someone has a better idea. At least the computer was free.
