   2 Subject: fix an incorrect IO error reading SMART status
   3 Description: The read SMART status command's return status
   4  was testing for a success/failure value that included 8
   5  bits that are "N/A" according to the standard, and required
   6  that they be zeros.  At least some drives do not fill them
   7  with zeros, so correct this by masking off the undefined
   8  bits.
