Check my other post regarding this. Dump won't clone wholedisks. It will clone filesystems (with all metadata intact).
The problem with a broken disk is that your filesystem may not be correct. And you can't do a fsck to correct the inconsistencies because the disk is not reliable.
That's why you require something like ddrescue, so you can copy everything that is still accessible and fill the blank spaces in with zero-blocks. So it doesn't abort or truncate the output like dd, maybe dd conv=noerror is similar but ddrescue has other features like proper status info during copying and decreasing blocksize when blocks fail to be read.
I never tried ddrescue, so I can't comment.
But, as far as I remember, dump will only abort if you get an error on the writing side. Memory can be at fault here, tho.
