Power Management
What is SATA Link Power Management (as seen in powertop hints)?
hddtemp
hddtemp seems to handle SATA devices just fine:

SMART
Generally, '-d ata' is a sufficient descriptor of a device for smartd to handle it. Determine SMART capability with smartctl -i:
[recombinator](0) $ sudo smartctl -i /dev/sdc smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Model Family: Seagate Barracuda 7200.11 Device Model: ST31000340AS Serial Number: 9QJ0YTFN Firmware Version: SD15 User Capacity: 1,000,204,886,016 bytes Device is: In smartctl database [for details use: -P show] ATA Version is: 8 ATA Standard is: ATA-8-ACS revision 4 Local Time is: Tue Sep 30 05:29:37 2008 EDT SMART support is: Available - device has SMART capability.

Determine if the specific hard drive model is known via -P show (this is not necessary for SMART to be used):
[recombinator](0) $ sudo smartctl -a /dev/sdc -P show smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ Drive found in smartmontools Database.

To check SMART statistics for a drive, try smartctl -a:
