Grr. The return key should not be the same as Send.
I had some problems with clonehdd that turned out to be hardware issued: my
disks has somehow defaulted to PIO4 from UDMA which made this process run
so slow it would just quit with finishing.
Now things are more what I expect, completing a clone of my root disk in
524 minutes, down from multiple days?
But it still seems slow if the disks are 1.5Gb/sec SATA disks. Looking
around, it looks like this might be useful to speed things up.

How? The partitioning scheme does not make any serious difference to
transfer rates. That's much more affected by the filesystem, but even
there the limits are usually due to drive and controller hardware.
One thing the partitioning scheme can affect is alignment. In your
other mail, this was shown to be a 500G drive, which is almost certainly
not using 4K blocks, and so alignment is not a problem.
