I've been using Paragon as well, for even longer. Slow but far fewer failures.
I don't agree with that step. Cloning only needs a drive with a working filesystem, not a working OS, and for sector-by-sector cloning it doesn't even need a working filesystem. Attempting to repair an OS before cloning means you could potentially stop the OS working (e.g. if there are bad sectors you're not aware of). Far better to do those things AFTER cloning to a known-good drive, and while you still have the original drive if something goes wrong. And besides, the new drive is often faster so those repair operations will be faster done there.
