The ASC (Additional Sense Code) of 0x18 indicates a recovered media
error, and that the data was probably recovered with via some ECC
method.  The ASCQ (Additional Sense Code Qualifier) of 0x89 is in the
vendor-specific range, so it's difficult to decipher that one without
detailed device specs.

You most likely have a bad disk sector, which the drive is still able to
read using some variety of ECC.
