Balena Etcher - clone drive, now have two blank drives

Rich,

I have managed to do as instructed above on a mac device, I have the copy.img file but I keep getting this message
The only drive that was backed up was the C drive, is there a way to the rest of the drives.

as you can see in the screen shot disk3 os the physical one that was erased by the bug in the application
disk4 is the image mounted which is only drive C

as i recall they were 4 or 5 drives NTFS
What can I do ?
