xfs_check did move a few things around but finished fine

sudo xfs_fsr -v /dev/sdg1 <== This is just so far it is still running.

Now my issue is how do I fix it if xfs_repair doesn't see a problem.
Anything getting copied to the drive works fine in place wasn't until i
tried to move it off I noticed the issue. Some things copy fine from it
several others fail. Then i get Input/output error. It is a full 1tb drive .
WD mybook it lost power which I think is what caused this issue. How can I
correct the issue. Everything I try takes a hell of a long time and doesn't
yield a positive result
