The best way to do this depends upon whether you intend this to be a
one-time thing, i.e. take images of these three disks, put the images
back on the three disks and then never do this again.
*Or*, if you want to continually back up the three disks to the 1TB
drive such that at some point in the future presumably after some
disaster you could restore any of the images.
The second scenario really calls for some sort of actual backup
solution.
Also are these three disks currently in three operating bootable other
machines, or do you have three disks in one machine and you boot and
choose between them via the bootloader, i.e. only one of them is
in use at any given time?
And are all these disks in the same machine? Meaning that you have three
different bootable disks to choose from plus this other 1TB disk that
can be used but isn't something you boot into?
We really could benefit from knowing what you are trying to achieve
instead of your ideas of how some unstated thing could be achieved by
way of "ISOs".
Thanks,
Andy
