Anna,
Thanks again for clarifying several things that were bothering me regarding
the use of the external drive in a multi partition mode. Since I haven't
downloaded the Windows 7 OS yet, I don't know its footprint size. The XP
installation is about 40 gigs including all of my apps so I would guess that
the W7 installation sans apps would be less than that. I would think that 3
80 gig partitions on the external drive would be about right. I will let
you know how it works out when I finally decide to tackle it.

bobster:
Your having an external enclosure that has SATA-to-SATA connectivity
(presumably in addition to USB-connectivity) is really an ideal situation.
Since (AFAIK) your Dell Inspiron 530 is not equipped with an eSATA port it
didn't occur to me that you were working with that type of external
device.
I would guess that you've either installed a eSATA (or SATA) adapter in
the
desktop machine to achieve that capability or directly connect your
external
device to an available SATA connector on the motherboard.
In any event the fact that you can directly boot from the external device
is
certainly an advantage. And (usually) a SATA-connected HDD considerably
outperforms a USB-connected HDD assuming USB 2.0 capability. (Things may
dramatically change when we move to USB 3.0).
It's really a simple & straightforward matter using the XP Disk Management
snap-in to multi-partition the external HDD. You should have no difficulty
doing so. Since (I assume) you will be using the external HDD as your
"destination" drive you can start "fresh" so to speak and delete the
current
partition on that drive and then multi-partition the drive and finally
clone
the contents of the two OSs to the appropriate partition.
If & when the time comes when you need to directly boot to one of the two
cloned systems on the external HDD you would ordinarily use Disk
Management
to "Mark Partition as Active" (assuming that partition is not already
shown
as the "active" partition). All that's involved is a simple right-click on
the drive's listing and selecting the preceding command from the sub-menu.
And, of course, change the boot priority order in the BIOS upon bootup so
that the system will boot to the external disk.

Anna,
Yes, my Inspiron 530 did not have an eSATA port as delivered but when I
bought the full up WD 320 gig HD kit, it came with an eSATA cable and a
rear mounted port connector assembly for an external HD. The other end
connected to one of the unused SATA ports on my mother board. I've never
had any problem in booting from this HD which is mounted in an eSATA/USB
capable Vantec external enclosure.
I still have a few concerns about proceeding with the changes we have been
discussing. As I mentioned, I have 3 identical HDs, mounted in internal
position 1, internal position 2, and the Vantec mounted one. They each
have
been assigned a single drive letter (C, E, and F) although they each have
3
partitions. One of my concerns is if I use the external mounted one as my
destination drive, and re-partition it into 2 or more partitions, with 2
or
more new drive letters, each of those partitions will be smaller than the
size of the drive letter partitions on the two internal drives. Casper
will
probably tell me that there isn't enough free space to clone either
internal
drive to a partition on the external drive. If that happens I would
probably junk the whole process, especially if it meant I would have to
re-partition my internal drive to mirror my external destination drive.
I know the above sounds like the rantings of a novice in drive formatting,
but having a trouble-free XP/IE-8 system, I am reluctant to try and
re-format it's HD in order to accommodate a single HD backup system for XP
and Windows 7. Maybe I should just leave things as they are currently
configured, download Windows 7 onto my first internal HD, clone that to
the
Vantec external drive, then replace the HD in the Vantec with another 320
g
WD (which I already have) and clone the second internal drive (with
XP/IE-8
on it) to this HD. This sounds complicated but I can change a drive in
the
Vantec in about 5 minutes.
I'm going to "cool it" for a few days while I decide how to proceed as
there
is no hurry to do anything.
Any additional comments will be appreciated.

It seems to me that the most straightforward & efficient configuration in
your situation based upon your objective of working with two different
operating systems and having at your disposal two internal HDDs plus an
external HDD is to...
1. Install the XP system on one internal HDD.
2. Install the Win7 system on the other internal HDD.
3. Utilize your external HDD as the "destination" HDD, and use your Casper
disk-cloning program as the vehicle to contain the cloned contents of each
of the two internal HDDs. As I previously indicated you would
multi-partition the external HDD into two partitions to accommodate the
cloned contents of each OS.
Naturally this assumes that the 320 GB external HDD you're working with
contains sufficient disk space to contain those cloned contents. You haven't
indicated the total amount of data you're working with in each of those two
systems but I'm assuming each of the external drive's partitions you create
would be sufficient in size to accommodate the cloned contents of that
particular OS. Is that a reasonable assumption?
I'm also assuming each of your two internal HDDs will be single-partitioned.
Given the configuration I'm suggesting I see no reason to multi-partition
these drives.
Forget about drive letter assignments re the external HDD. They are of *no*
relevance in this situation. The same is true of your internal HDDs. As an
example...
Let's say your XP OS is installed on internal HDD #1 and your Win7 OS is
installed on internal HDD #2. Now you decide to boot to your XP OS. Assuming
the BIOS boot priority order indicates a first HDD boot to HDD #1 the system
will boot to that drive which of course will receive the C: drive letter
assignment.
Since your second internal HDD containing the Win7 is also connected as a
secondary HDD at this point it will receive a non-C: drive letter
assignment. Again the drive letter assigned to that drive during this
operation is of no consequence based upon what we are discussing.
Let's say at another time you now desire to boot to your Win7 OS. Assuming
the BIOS boot priority order indicates a first HDD boot to your HDD #2, the
system will boot to that drive which of course will receive the C: drive
letter assignment. Since your first internal HDD containing the XP OS is
also connected as a secondary HDD at this point it will receive a non-C:
drive letter assignment. Again, the drive letter assigned to that drive,
i.e., "HDD #1" during this operation is of no consequence based upon what we
are discussing.
And so on & so on...
Now let's say that while you've booted to your XP OS ("HDD #1"), you decide
to clone the contents of that drive to one of the two partitions you
previously created on your external HDD. Understand that when you originally
multi-partitioned that external HDD into two partitions the drive letters
assigned to each of those partitions is of no consequence in terms of our
present discussion except in "telling" Casper which partition should act as
the destination drive for the purposes of receiving the cloned contents of
your HDD #1. Let's say, as an example, you will be cloning the contents of
that drive to the F: partition on the external HDD, the other partition
having been assigned the G: drive letter assignment.
You will use the same basic process to clone the contents of your Win7 OS
contained on internal HDD #2, but this time using the "G:" partition as the
recipient of those cloned contents.
So now you have your external HDD containing the cloned contents of your XP
& Win7 systems. The fact that the two partitions on the external HDD have
been designated F: & G: are really of no relevance here. Since your external
HDD is a bootable device you will be able to boot to either of the OSs
contained on the external HDD. Let's say you desire to boot to the cloned XP
OS contained on partition F:. (As I previously indicated you will have to
first ensure that the selected partition is marked "Active"; I previously
explained that simple process using Disk Management) . Then ensure that the
BIOS boot priority order indicates a first HDD boot to your external HDD.
The system will then boot to the cloned XP OS on your external HDD and
receive a C: drive letter assignment. The partition containing the cloned
Win7 OS will receive a non-C: letter assignment, possibly retaining the G:
drive letter assignment. In any event the drive letter assigned to the
latter partition is of no relevance re our discussion.
Once again, you would follow the same basic process should you desire to
boot to the cloned Win7 OS on the external HDD. Again ensuring that the
partition containing that OS is marked "Active" and the BIOS boot priority
order indicates a first HDD boot to your external HDD.
Obviously there are different approaches one can take to meet your
objectives but as I stated I believe the approach I'm suggesting is a
sensible one under your circumstances.
