DDRescue will be okish in linux but can be damaging to your drives without an improved script. Such as to control reading of bad sectors, retries, stop or other option you want.
Norton Ghost isn’t a good sector imager, i wouldn’t use it.
Acronis True Image is good for windows drive imaging. Version depending i heard they did one or a tool that can do sector imaging (not tried). Acronis True Image does hash images not sector based, so no good. Try find their sector based one and try that instead.
Not used or tried any of te others, unless they are known by different names.
For drive contents to be imaged or clone you need to read/write drive sectors. Google for hd sector image clone you wil find many to try or use. Do it now and practice on two drives that don’t matter for the data contents. Be better prepared, when needing to do it for real.
