Hopefully someone will have a solution but I think you are outta luck John. I know that drive and you're right it's indeed set up to run on a Windows machine.
The Apple Time Capsule (being your best choice for network storage) doesn't even format through Apple's Disk Utility, it's erased, formatted and set up all through Apple's Airport Disk Utility which has special software for the Time Capsule since it connects via Ethernet like the MyBook.
For future purchases I would highly recommend buying external devices that are not just Mac OS or Windows specific because your chances are very slim you will be able to find drivers to convert them.
You may have had a chance if the connection was done through USB or Firewire.
