First of all, lots of thanks for taking the time to help.

Then, I really understand very little, if any, of computer hardware and/or  
systems programming. Given that, I dare ask a naive question: Could the  
problem be because of running a "32-bit virtual machine" on a "64-bit OS?"

The version of VPC I am using is supposed to be 64-bit. Microsoft's  
website says so. And the 32-bit version I had would not even install on  
Windows XP x64. In spite of these facts, Windows task manager adds a *32  
to the image name of the VPC process which effectively means it is a  
32-bit process running in compatibility mode. The emulated machines are  
surely 32-bit.

On the other hand, my (32-bit) FreeBSD installation is running prefectly  
OK on this same platform.

Right now, I think one way to test any ideas is for me to boot into the  
live system and somehow try to access the virtual hard disk. I would be  
grateful if someone would instruct me on any diagnostic procedures and/or  
various access methods from the live system. Things equivalent to the  
UNIX/Linux mount, mkfs, and fsck.
