Thanks for your tips! I guess it would be an even longer way to go than I first thought. I think it is easier to do than to explain :-)

The issue of sector size I would like confirmation from others. I don't know if is possible to clone (dd) a disk using dd when the source uses 4 KB sectors and the destination 512 bytes. All my current big hard disks use 4 KB sectors, and all my SSDs, smaller, use 512 bytes.

It depends. Most 4k disks have an emulation built in to allow 512 byte sector size, so from the outside, they can be viewed as disks haveing that sector size. Agreed: when you change a single 512-byte sector, the disk itself has to read 4k, then modify the 512 bytes and then write the 4k back, but that is invisible (but measurable) from the outside.
