I'm still trying to wrap my poor mind around this stuff, because I
can't get any raw partitions to work under Windows :^(  I've
received a number of helpful private e-mails which I haven't had
time to follow up on (you know who you are, thank you :^).

If I understand, Windows doesn't "count" /dev/hda3 a.k.a. the Extended
partition.  \D\H\P0 is the whole disk, then it assigns the devices from 
\D\H\P1 through 5 in order of the partition table's numbering, but 
skipping the Extended partition.  Can someone with more experience please 
confirm this is the way Windows assigns \Device\HarddiskX\PartitionY?

Two other newbie-type questions:

1.) Is the primary master IDE disk Harddisk0, the primary slave Harddisk1, 
the secondary master Harddisk2, and the secondary slave Harddisk3?  This 
would agree with the info on this MS Technet page:

http://www.microsoft.com/technet/prodtechnol/winntas/maintain/manag.mspx

(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:

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:

http://users.erols.com/gmgarner/forensics/).

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