I'm using 10.4.11 on my MDD G4 (dual 867). The other day I booted into 9.2 to use a particular program. When I rebooted back into Tiger, I could not access the Internet (even though Network utility said I had an IP address and was connected), then I found that USB storage devices would not mount, nor would any CD or DVD. I reinstalled Tiger (after running Disk Utility) and the problem is the same. I can't get anything in or out of the computer now.
