Yeah, to a Linux expert probably. But when I looked at an instruction
on the web on how to do a mirror archive of a Windows machine using a
Knoppix CD in order to dump that back onto a new hard drive that was
at least two pages of intricate command line stuff.

You can do it in one line using e.g. ntfsclone. That's what I use to
image laptops in their pristine state, before giving them to the
user. The man page for ntfsclone gives the required command line for
the most common scenarios (backup, restore, to/from a local file, and
to/from the network.

Thanks, John, that doesn't sound too difficult. I hope it allows to
choose the password, else I'd be stuck.

The password is only used when you want to backup to a remote machine
via the network, using the ssh protocol. You would also need that
remote machine, with a suitable ssh server (like many linux boxes have
for remote admin). This scenario is what these command line versions
address:

ntfsclone --save-image --output - /dev/hda1 | \\
gzip -c | ssh host ’cat > backup.img.gz’

Restore an NTFS volume from a remote host via ssh. Please note, that ssh may ask for a password!

ssh host ’cat backup.img.gz’ | gunzip -c | \\
ntfsclone --restore-image --overwrite /dev/hda1 -

What it is doing is setting up a "pipeline" so that data goes:

ntfsclone <-> gzip <-> ssh client <-> network <-> ssh server <-> remote file

But for it to work you have to have the remote machine setup right too
(e.g. with linux, with the ssh daemon running).

But if at all possible I suggest you hook up two drives in parallel,
and just copy from one to the other, since it sounds like you would
find it easier to configure this. Then you would use the command line:

Clone NTFS on /dev/hda1 to /dev/hdc1:

ntfsclone --overwrite /dev/hdc1 /dev/hda1

Of course you had better be sure which one is hdc1 and which one is
hda1.

Not of this is particularly difficult if you are familiar with linux,
but could be a time waster if you are not i'm afraid.

The other issue is whether the HD wakes up one more time. When I
wanted to save one last bit of personal information (TB address
book) it came back with some obscure "missing string" error.

I'm not sure how well ntfsclone copes with filesystem errors. I have
only used it on intact filesystems, to image a working, setup system
for later recovery. There are other more basic commands which can
literally "clone" a hard disk, errors and all, such as dd.
