A safe way to clone hard disks goes like so:
1. Create the clone.
2. Disconnect the cloned disk.
3. Boot each disk on its own, without the other connected.


   Yes, that is "a safe way".  But it's not the necessary way.
   What is necessary is that the new clone - when booted for
   its *1st time* - does not see it "parent" OS, the one it was
   cloned from.  Thereafter, it *can* be booted with its
   "parent" visible to it, and it will only see its "parent" as
   just another Local Disk, perhaps calling it "D:", and containing
   a file structure that is accessible to it.  But with the "parent"
   OS, booting can be done at any time without any harm,
   and it will likewise see the clone as being just another
   Local Disk, perhaps calling it "D:", and containing a file
   structure that is accessible to it.  The running OS calls its
   partition "C:" in its Disk Management utility, and the other
   partition it usually calls "D:" unless there are more partitions
   around.  In my system, which has many clones on 3 HDs,
   I've seen cloned paritions named with letters all the way
   out to "K:" while the running OS always calls its own
   partition "C:".
