phantom clone partition mounted at J: as system boot drive

I have an obscure issue which has me baffled and, which I am hoping someone
can help me resolve. The problem is that the C: system partition although
present on the computer has been replaced in the registry by an identical
clone mounted as J:. Changes to either drive seem to be replicated on each
other, but there are networking and path problems.

This came about as I was upgrading the system by migrating the system to a
larger drive, as the original XP installation had only 300MB left and this
was causing some problems. Except for the small amount of free disk space,
the machine was very stable and had a lot of applications configured which
meant a clean install would have been a very tedious slow process.
Originally, the C; partition was on what is now the 9.55GB E: drive (this was
partitioned 8GB C System and 1.55GB D: Swap and set as primary master and
the 18.65GB primary slave was the E: drive) so my upgradde plan was to create
an image of the C: System partition and then reconfigure the primary master
and slave drives.

I did this by firstly creating a full backup image of the C; system drive
using Macrium Reflect version 2.2 (which was on the machine) and backing up
the contents of the E: drive. I then swapped jumpers to make the 18.65GB disk
the primary master and the 9.5GB disk the slave. I then started teh machine
using a BART PR disk which had the Macrium plug-in for BART PE installed.
This alowed me to format the drives into thenew configuration (C: 16.5GB
system partition and D: 2.14 GB Swap partition on the 18.65GB drive now at
primary master and E: Work on the 9.55GB drive now at primary slave) and then
to restore the backup image of the C: drive to the new C: location. all
seemed to be fine and so I restarted teh machine normally.

When the machine restarted, everything was fine, the log-on screen appeared
with the username and domain exactly as it had been at the previous log-on,
but when I entered the password and logged on, the screen displayed an error
message "A problem is preventing Windows from accurately checking the license
for this computer. Error code: 0x80090006" which I looked up. The suggested
solutions related to using either Ghost or Image Drive Pro, which I had no
used, so I took the alternate solution of an inplace upgrade repair using the
original windows xp pro installation disk.

After the repair installation was complete, I again started the computer and
it loaded up as normal, brought up the log-on screen with username and
domain from last log-on, and started perfectly, or so it appeared. Up popped
a couple of missing parth errors, so I opened windows explorer to try and see
if everything was as it should be. It all seemed fine until I noticed the J:
System Drive, and saw that it was an exact clone of the C: drive. I opened
the command prompt and the window opened at J:\documents and settings\etc. I
looked at the environment variable and discovered that everything was
pointing to J: instead of C: and so I wend through the registry and found
that almost every entry which should have started with C:, was starting with
J:.

Can anybody suggest a fairly effortless way of unmounting the j: drive and
restoring the c:drive as the active system drive. It would save me a headache
as the machine cannot be returned to service until it is properly sorted.
Anyone coming up with the correct solution, will be added to my list of

Your dilemma may have originated when you first cloned the older hard
drive to the newer larger one. Once the clone was completed, you
should have disconnected the old small hard drive and reconfigure the
new drive as the sole master drive. Once the newer driver had booted,
you could then re-install the older drive as slave.

When XP boots with two drives set to start XP, most XPs get confused.
 
It's a write off, start again and reclone the old "C" drive to the new
one, this time *before* you boot the clone for the first time go in the
BIOS and disable all the other hard drives or open the case and unplug
the power to all but the newly cloned drive, you don't want the clone to
see the other drives when it boots for the first time, after the clone
has been booted once you can then enable or reconnect the other drives.

What you are seeing is a well known issue with cloned drives, the Mount
Manager keeps a database of previously assigned drive letters and it
persistently reassigns the previously assigned letters to the same
drives, when you booted the clone the Mount Manager assigned the drive
letters based on the information in its database and assigned the C:
letter to the same old drive so it had to use the next available letter
for the newly cloned drive. This could have been fixed fairly easily if
you hadn't performed an in-place upgrade (repair install), an in-place
upgrade re-enumerates the disks and forces new drive letter assignments,
now the changes made cannot be reversed, only a clean install or a
recloning of the old drive will fix things.

On thing that isn't quite normal is the behaviour of the C: and J:
drives that you describe. If I understand your explanation correctly
you are saying that any changes that you make on one drive or the other
is automatically replicated to the other drive, if I understand this to
be the case if you delete or create a file on one drive it is
automatically deleted or created on the other drive? This would
indicate that you have an NTFS Junction Point between these two drives,
this isn't quite normal, Junction Points are not usually created without
specific user input and it is rather difficult to create Junction Points
without the use of special tools or commands, I can't understand how
they would have come to be. See here for more information on how to
identify and remove these Junction Points:

http://support.microsoft.com/kb/205524
http://technet.microsoft.com/en-us/sysinternals/bb896768.aspx

Removing Junction Points (if they are present) will not fix the drive
letter mixup caused by the reinstallation, you have to start again from
scratc to fix that problem.

Thanks for the help - I have 2 new all time heroes. I recloned the c: drive
and selected the option to use a standard windows xp mbr rather than the
existing mbr or the mbr in the image. I shut down the machine, disconnected
the power connectors from all the other HDDs and then botted up. I logged on
without problems all my old desktop configuration coming up as before. I shut
down again, reconnected the HDDs and rebooted and everything is back up as it
should be but with 8.5 GB free space on the system drive and plenty of room
to work.

As for the NTFS junction, don't ask me how I did it, but yes I ceated a file
test.txt on the c: drive and it was there on the j: drive. I opened it and
wrote the word test, saved and closed it and opened it on the c: drive and
the change was there. I then deleted it and it was gone from both. I don't
think I could reproduce it if I tried, but it must be possible, but to what
benefit, I don't know.

Anyway, my very grateful help for your advice.
 
You're welcome. As for the NTFS junction it could very well be that one
of your programs could have created it.

John
 
Oh, and by the way, that other drive could also be a "substituted"
drive, some older programs like to work with substituted drives. You
can find these drives by issuing the SUBST command at a Command Prompt.
