I have the problem that I am trying to clone a source volume that is a Time Machine volume on a failing disk. The drive will mount after a few minutes with a message from "Disk Repair" saying the volume could not be repaired and is being made available with limited functionality.

Part of that limited functionality is that it appears to the system as not being journaled. This causes SuperDuper to erase the target to be non-journaled, and then the copy fails because it says the Time Machine hard links require a journaled format. Disk Utility cannot enable journaling on the volume because of the problem.

I can't seem to figure out how to keep SD from formatting the target, which would seem to be an easy way around this.
