When I think of clone (which I've never done), I think of something that
is identical. Does the best way to make a clone involve using the same
make and model of the hard drive? What happens if the size of the drive
is different?


Daave:
For all practical purposes, a disk clone is a clone is a clone is a clone.
While it is true that the cloned contents of the source HDD residing on the
destination HDD will not be an *exact* bit-for-bit copy of the source drive,
it is a true copy in every practical sense of the word, i.e., it will be
bootable and function precisely the same way as the source from which it was
cloned.

So you (and Rock) are right to think of a disk clone that, again, for all
practical purposes, is "identical" or an "exact reproduction".

With modern disk cloning/disk imaging programs such as Symantec's Norton
Ghost, Acronis True Image, Casper, etc., there is no need for the
destination HDD to be the same make and/or model of the source disk. All
that is necessary is that the destination drive contain sufficient disk
space to hold the cloned contents of the source drive. So, for example, if
your source HDD was 250 GB but contained only 110 GB of data, there would be
no problem cloning the contents of source drive to a 160 GB HDD.

Many users, we among them, use the disk cloning capability of a disk imaging
program for routine backup purposes. While it is true that (generally)
creating a disk-to-disk clone takes longer than creating a disk image, there
are certain advantages to the disk clone - one of which is that all the data
is immediately available on the recipient (destination) HDD. No recovery
process is necessary as one needs to undertake re the restoration process
involving one or more disk images.

The disk cloning program we are currently using and which we've been very
impressed with it the Casper 4.0 program (http://www.fssdev.com) . Perhaps
you've come across my recent detailed account of this program that I believe
I posted to this newsgroup. It's one you should look into if you're
interested in a disk cloning program.
