>>I'm thinking that I might have to "manually" mount the hard drive with some utility, but am not sure if such a thing exists. Alternately, I am thinking that Norton Utilities, TechTool or something else might be necessary here... any suggestions?<<
Okay, I have found a bootable copy of Norton 6.0.2, and managed to fix a host of problems.... including the odd configuration wherein "There is no blessed folder, but there seems to be a System Folder." Upon fixing this, the drive mounted and now I can access it while booted off of the Norton CD.
However, upon rebooting from the newly-repaired drive, I get not the blinking blue folder/question mark situation, but a blinking floppy, and what sounds like my internal drive spinning and then stopping, spinning and then stopping consistently.
