Ok.  I'm pre-coffee... so...  18 years huh?   Then why didn't you 
bother to say that the apps themselves don't work????  That does 
kindof change the WHOLE nature of the issue... </rant>

Except that you have fatal i/o error on the source and your 
destination is obviously corrupted, since apps aren't working right.

No, not busy.

It means rsync tried to read the data from the HD and it FAILED.  The 
hard drive refused to provide the data because of a FATAL error. 
Either the hard drive had a controller problem or the the data blocks 
involved have become unreadable.  Further details might be available 
in your system log.

IFF (If and ONLY if) it's just those files or directories involved, 
then yes.  BUT given your other issues, I'm wondering what else has 
died on that drive.

I'm thinking you need to find out how bad the problem is.  It may be 
that your source drive is dying.  It may be that the media just grew 
a few bad blocks.  You need to get your user data backed up, check 
the log files, then repave that whole drive (all its volumes).  Erase 
/ Zero it, at least two passes, to make sure all the bad blocks get 
mapped out.  Check the logs to make sure there were no fatal 
controller errors.  If none, then it might be safe to reload it from 
scratch.

...If the backups you have are block-level clones, then you might not 
be able to trust them!  A perfect copy of corrupted data is itself 
corrupted...
