Possibly our default SEND_DIAGNOSTIC should turn into smart or just
return whether the drive failed the power up diagnostic ?

Either/or. In general the SAT (SCSI/ATA translation) spec posted publicly on http://www.t10.org/ gives the suggested transformation into ATA commands. And yep, you guessed it -- send diag morphs into SMART.

I doubt I'm motivated enough to enhance send diag, but others are encouraged to do so.
