Handling and reporting error conditions relating to the updating of S.M.A.R.T.
logs and S.M.A.R.T. Attributes is accomplished the same as handling error
conditions experienced while saving user data. Likewise, handling and reporting
error conditions relating to other processes (including background processes)
that occur while updating S.M.A.R.T. logs and S.M.A.R.T. Attributes is
accomplished the same as handling such error conditions while saving user data.
S.M.A.R.T. logs are validated by affecting the events being detected and logged;
the S.M.A.R.T. log always reflects the event that occurred, whether that event is
injected artificially or occurs independently.
