A clone of a hard disk is only useful if you want to store the actual structure of the files on the hard disk - something you very rarely need to do. On a PC it does guarantee that you're getting what you expect (Windows is so complicated it'd probably get confused with file copies) but on an Amiga you really don't need it.
Connect source HD0: to IDE bus (or anywhere else)
Connect target HD0: to IDE bus (or anywhere else)
Boot HD0:
Newshell
Copy HD0: HD0.1: all clone quiet
Remove source HD0:
Done. This will also defragment your hard disk in the process (not that helps much if it's solid state, but still....)
If you really want to clone your disk, you'll need any disk-imaging program which allows variable device names and specifications - I think Quarterback Tools would do it, and there will be others.... but it's really not necessary except in very special circumstances.
