Looks like the drive reports ERR/ABRT (command aborted), meaning it likely doesn't support those commands.

Except the PATA version of the drive does (same capacity, & other specs). Seagate would disable "advanced" features for SATA but leave them for the older technology? Possible,
but doesn't seem likely.

If this is a Seagate, I believe that they don't have AAM enabled on any of their newer drives (something about a lawsuit for patent infringement on that feature, or something). Quite likely they don't support that power management command, either.
