ARRE only works if the data is recoverable, and AWRE only works on
writes, so if the bad block has already been assigned to a file, it's
difficult to fix unless you know the filename.  You can try doing a
"tar xvfl /dev/null /mountpoint" and see where it stops, then dd
/dev/zero onto the file to force a write. Another way is to get the
drive to check all the blocks on the disk by running a Verify operation
from your SCSI BIOS.
