I have three different Dell desktops. They are running FC5, FC6, and F7, respectively. I mention this because the problem does not occur on FC6. I have Western Digital USB drives with ext3 filesystems attached to each. On the FC5 and F7 machines the boot process fails to mount the USB drive. There is some complaint about an invalid ext3 filesystem. But, after the machines are fully booted, I can mount the USB drives without any problem. Is the mount being attempted before the drivers are in place? Is there a way to resolve this problem?
