Well, no.
If there are bad sectors, there are issues in the hardware (electronics) not in the filesystem (logic), or not only in it.
A forensic tool such as the FTK imager is suitable for working hardware, just like "plain" dd.
Recovery tools such as ddrescue and similar are intended to rescue or recover as much data as possible and they usually do a good work, but they cannot obviously do miracles with failing or failed drives that may need - where possible - hardware or firmware repairs.
Interpreting the (partial) data that you may obtain through the recovery of good sectors is another thing, for which the mentioned DMDE is suited, but of course you need to know where your towel is.
The Stellar Info thingy is (for my personal tastes) a bit too "automagic".
