I recall some very confusing names in the whole *dd*rescue app area.  Is 
one of the ones you are trying this one?
	gddrescue: a tool for recovering data from damaged media

Also, what does "rescue user files" mean?  Deleted?  Bad disk?  Other? 
Depending on that answer *dd*rescue may be overkill.  I've used foremost 
to recover deleted files [1].

foremost: Forensics application to recover data
autopsy: graphical interface to SleuthKit [digital forensics tools]

Good luck,
[1] $ sudo foremost -v -t jpg -i /dev/sdb1 -o .
Note this was a camera and thus a FAT file system, so YMMV.
