Huge drawback of HD Sentinel for that particular feature: it will actually try to access the defective sectors and display their contents when requested to display which files they belong to. Piriform's Defraggler is excellent for that purpose, in combination with the LBA values of bad sectors provided by HD Sentinel during its scan: point a block on the map and it lists which files are in that area. But the first step should be cloning/imaging, and as Scott Petrack mentioned, it's possible to get a list of files affected by bad sectors by using ddru_ntfsfindbad in combination with ddrescue.

nfi.exe does not have this issue, it gives its results by analysing the MFT and does not attempt to access the requested sectors, but there seems to be an issue with values beyond 2^31 or 2147483648. superuser.com/questions/1267334/… The native multi-purpose Windows tool fsutil doesn't seem to have that issue, and the output is more streamlined, but it's slower (can be a problem if there are many clusters to request). With nfi use sector numbers, but with fsutil use cluster number.
