Hi Sam,
Good question!
The SMART enable/disable attribute autosave was NEVER part of the ATA
spec. However it was part of the SFF-8035i spec that was later
incorporated into ATA-3. Please see
ftp://ftp3.ds.pg.gda.pl/people/macro/S.M.A.R.T./8035R2_0.PDF
for details, and in particular page 10.
The smartctl man page also has some details about this.
Cheers,
Bruce
