Yes.  Something like DiskWarrior should never be used to try to repair 
on a failing disk.  They are only useful for a damaged file system that 
not sustaining more damage as it works. They tend to assume this.
Once the disk itself starts to fail, trying to fix things usually 
simply makes things
worse, and you lose more files faster.  You can use some of these 
to try to retrieve data - but never let them actually write to the disk.

SOP would be to make a block for block copy of the disk onto another 
and run a file syste repair utility on the copy.  Never run it on known 

Just get the good data off NOW!
