I have a toshiba qosmio x770 with ubuntu 12.04 64 bit and when I run HDAPSD, the output is:

Sat Aug 25 03:20:31 2012: Starting hdapsd
Sat Aug 25 03:20:31 2012: WARNING: You did not supply any devices to protect, trying autodetection.
Sat Aug 25 03:20:31 2012: Adding autodetected device: sda
Sat Aug 25 03:20:31 2012: Could not find a suitable interface

in windows worked perfectly HDD protection

what can I do?
