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