You need to look at things from a logical point of view and not
physical.

Yes. But logical, not physical.

(except for the typo under "IDE Drives" where they say the first drive
on the second controller would be designated 3, not 2 -- oops).

2.) Do the \Device\HarddiskVolumeX designations come from the Logical
Disk Manager?  And how do you figure out the mapping of 
\D\HarddiskVolumeX to \D\HarddiskY\PartitionZ?  The port of dd to
Windows with the --list option available here:
Yes, use logical disk manager. Hard disks start at 0. Partitions start
at 1. Personally I dont see how using a *nix orientated utility can help
in this matter.

http://uranus.it.swin.edu.au/~jn/linux/rawwrite/dd.htm

doesn't list the HarddiskVolumeX designations.  (Another place to get a
dd port to Windows is:

If this is a FAQ or RTFM, please say so and I apologize in advance :^P
