OK.
Can I dd copy them to .isos on the 1 Tb disk then put them back on
other
disks so they boot?
Ah, you mean one of them is your OS disk, and that you want to remove
that
OS disk and put in a new OS disk.
I apologise for not being clear in my question I should know by now not
to post if "tired".
For the purpose of backing up 3 ~200Gb disks, with Debian operating
systems on them, I wondered if I can put them all on one 1Tb disk and be
able to copy them back.
Not really understanding how dd works wondered if a bootable disk can be
copied to a partition on another disk for the purpose of backup.
Or if the disks should be copied to ISOs. I've not done that before.
